The invention also relates to the use of the 2-cyanobenzenesulfonamide compounds, of their salts or of compositions comprising them for combating animal pests.

Animal pests destroy growing and harvested crops and attack wooden dwelling and commercial structures, causing large economic loss to the food supply and to property.

While a large number of pesticidal agents are known, due to the ability of target pests to develop resistance to said agents, there is an ongoing need for new agents for com- bating animal pests. In particular, animal pests such as insects and acaridae are diffi- cult to be effectively controlled.

EP 0033984 describes substituted 2-cyanobenzenesulfonamide compounds having an aphicidal activity. The benzenesulfonamide compounds preferably carry a fluorine atom or chorine atom in the 3-position of the phenyl ring. However, the pesticidal activity of said compounds is unsatisfactory and they are only active against aphids.

It is therefore an object of the present invention to provide compounds having a good pesticidal activity, especially against difficult to control insects and acaridae.

It has been found that these objects are solved by 2-cyanobenzenesulfonamide com- pounds of the general formula I where R'is C,-C4-alkyl, C,-C4-haloalkyl, C,-C4-alkoxy or C1-C4-haloalkoxy ; R2 is hydrogen, C1-C6-alkyl, C2-C6-alkenyl, C2-C6-alkinyl, C3-C8-cycloalkyl or Ci-C4- alkoxy, wherein the five last-mentioned radicals may be unsubstituted, partially or fully halogenated and/or may carry one, two, or three radicals selected from the group consisting of C1-C4-alkoxy, C1-C4-alkylthio, C1-C4-alkylsulfinyl, C,-C4- alkylsulfonyl, C1-C4-haloalkoxy, C1-C4-haloalkylthio, C1-C4-alkoxycarbonyl, cyano, amino, (C1-C4-alkyl) amino, di- (Cl-C4-alkyl) amino, C3-C8-cycloalkyl and phenyl, it being possible for phenyl to be unsubstituted, partially or fully halogenated and/or to carry one, two or three substituents selected from the group consisting of Ci-

C4-alkyl, C1-C4-haloalkyl, C1-C4-alkoxy, C1-C4-haloalkoxy ; and R3, R4 and R5 are independently of one another selected from the group consisting of hydrogen, halogen, cyano, nitro, C1-C6-alkyl, C3-C8-cycloalkyl, C1-C4-haloalkyl, C1-C4-alkoxy, C1-C4-alkylthio, C1-C4-alkylsulfinyl, C1-C4-alkylsulfonyl, C1-C4- haloalkoxy, C1-C4-haloalkylthio, C2-C6-alkenyl, C2-C6-alkinyl, C1-C4- alkoxycarbonyl, amino, (C1-C4-alkyl) amino, di-(C1-C4-alkyl) amino, aminocarbonyl, (C1-C4-alkyl) aminocarbonyl and di- (Cl-C4-alkyl) aminocarbonyl ; and by their agriculturally acceptable salts. The compounds of the formula I and their agriculturally acceptable salts have a high pesticidal activity, especially against difficult to control insects and acaridae.

Accordingly, the present invention relates to 2-cyanobenzenesulfonamide compounds of the general formula I and to their agriculturally useful salts.

Moreover, the present invention relates to the use of compounds I and/or their salts for combating animal pests; agricultural compositions comprising such an amount of at least one 2-cyanobenzenesulfonamide compound of the formula I and/or at least one agri- culturally useful salt of I and at least one inert liquid and/or solid agronomically acceptable carrier that it has a pesticidal action and, if desired, at least one surfactant; and a method of combating animal pests which comprises contacting the animal pests, their habit, breeding ground, food supply, plant, seed, soil, area, material or environment in which the animal pests are growing or may grow, or the mate- rials, plants, seeds, soils, surfaces or spaces to be protected from animal attack or infestation with a pesticidally effective amount of at least one 2-cyano- benzenesulfonamide compound of the general formula I and/or at least one agri- culturally acceptable salt thereof.

In the substituents R'to R5 the compounds of the general formula I may have one or more centers of chirality, in which case they are present as mixtures of enantiomers or diastereomers. The present invention provides both the pure enantiomers or di- astereomers or mixtures thereof.

Salts of the compounds of the formula I which are suitable for the use according to the invention are especially agriculturally acceptable salts. They can be formed in a cus- tomary method, e. g. by reacting the compound with an acid of the anion in question.

Suitable agriculturally useful salts are especially the salts of those cations or the acid addition salts of those acids whose cations and anions, respectively, do not have any adverse effect on the action of the compounds according to the present invention, which are useful for combating harmful insects or arachnids. Thus, suitable cations are

in particular the ions of the alkali metals, preferably lithium, sodium and potassium, of the alkaline earth metals, preferably calcium, magnesium and barium, and of the transi- tion metals, preferably manganese, copper, zinc and iron, and also the ammonium ion which may, if desired, carry one to four C1-C4-alkyl substituents and/or one phenyl or benzyl substituent, preferably diisopropylammonium, tetramethylammonium, tetrabu- tylammonium, trimethylbenzylammonium, furthermore phosphonium ions, sulfonium ions, preferably tri (C1-C4-alkyl) sulfonium, and sulfoxonium ions, preferably tri (Ci-C4- alkyl) sulfoxonium.

Anions of useful acid addition salts are primarily chloride, bromide, fluoride, hydrogen sulfate, sulfate, dihydrogen phosphate, hydrogen phosphate, phosphate, nitrate, hy- drogen carbonate, carbonate, hexafluorosilicate, hexafluorophosphate, benzoate, and the anions of C1-C4-alkanoic acids, preferably formate, acetate, propionate and bu- tyrate. They can be formed by reacting the compounds of the formulae la and lb with an acid of the corresponding anion, preferably of hydrochloric acid, hydrobromic acid, sulfuric acid, phosphoric acid or nitric acid.

OCClF2 (C2H50) 2CH-CH2- The 2-cyanobenzenesulfonamide compounds of the formula I can be prepared, for example, by reacting a 2-cyanobenzenesulfonylhalide 11 with ammonia or a primary amine (III), similarly to a process described in J. March, 4' edition 1992, p. 499 (see Scheme 1).

Scheme 1:

(II) (I) In Scheme 1 the variables R'to R5 are as defined above and Y is halogen, especially chlorine or bromine. The reaction of a sulfonylhalide 11, especially a sulfonylchloride, with an amine III is usually carried out in the presence of a solvent. Suitable solvents are polar solvents which are inert under the reaction conditions, for example C,-C4- alkanols such as methanol, ethanol, n-propanol or isopropanol, dialkyl ethers such as diethyl ether, diisopropyl ether or methyl ter-butyl ether, cyclic ethers such as dioxane or tetrahydrofuran, acetonitrile, carboxamides such as N, N-dimethyl formamide, N, N- dimethyl acetamide or N-methylpyrrolidinone, water, (provided the sulfonylhalide 11 is sufficiently resistent to hydrolysis under the reaction conditions used) or a mixture thereof.

In general, the amine III is employed in an at least equimolar amount, preferably at least 2-fold molar excess, based on the sulfonylhalide 11, to bind the hydrogen halide formed. It may be advantageous to employ the primary amine III in an up to 6-fold mo- lar excess, based on the sulfonylhalide 11.

It may be advantageous to carry out the reaction in the presence of an auxiliary base.

Suitable auxiliary bases include organic bases, for example tertiary amines, such as aliphatic tertiary amines, such as trimethylamine, triethylamine or diisopropylamine, cycloaliphatic tertiary amines such as N-methylpiperidine or aromatic amines such pyridine, substituted pyridines such as 2,3, 5-collidine, 2,4, 6-collidine, 2, 4-lutidine, 3,5- lutidine or 2, 6-lutidine and inorganic bases for example alkali metal carbonates and alkaline earth metal carbonates such as lithium carbonate, potassium carbonate and sodium carbonate, calcium carbonate and alkaline metal hydrogencarbonates such as sodium hydrogen carbonate. The molar ratio of auxiliary base to sulfonylhalide 11 is preferably in the range of from 1: 1 to 4: 1, preferably 1: 1 to 2: 1. If the reaction is carried out in the presence of an auxiliary base, the molar ratio of primary amine III to sulfonyl- halide 11 usually is 1: 1 to 1.5 : 1.

The reaction is usually carried out at a reaction temperature ranging from 0°C to the boiling point of the solvent, preferably from 0 to 30°C.

If not commercially available, the sulfonylhalide compounds 11 may be prepared, for example by one of the processes as described below.

The preparation of the sulfonylchloride compound 11 can be carried out, for example, according to the reaction sequence shown in Scheme 2 where the variables R', R3 to R5 are as defined above: Scheme 2: (IV) (V) (Id, Y = Cl) a) conversion of a benzisothiazole IV to a thiol V, for example, in analogy to a proc- ess described in Liebigs Ann. Chem. 1980,768-778, by reacting IV with a base such as an alkali metal hydroxide and alkaline earth metal hydroxide such as so- dium hydroxide, potassium hydroxide and calcium hydroxide, an alkali metal hy- dride such as sodium hydride or potassium hydride or an alkoxide such as so- dium methoxide, sodium ethoxide and the like in an inert organic solvent, for ex- ample an ether such as diethyl ether, diisopropyl ether, tetrahydrofuran, dioxane, or in a alcohol such as methanol, ethanol, propanol, isopropanol, butanol, 1,2- ethanediol, diethylene glycol, or in a carboxamide such as N, N-dimethyl forma- mide, N, N-dimethyl acetamide or N-methylpyrrolidinone or in dimethylsulfoxide or in a mixture of the above mentioned solvents; and acidification to yield the thiol V.

The benzisothiazole IV can be prepared in analogy to a process described in Liebig Ann. Chem 729,146-151 (1969); and subsequent b) oxidation of the thiol V to the sulfonylchloride 11 (Y = CI), for example, by reacting the thiol V with chlorine in water or a water-solvent mixture, e. g. a mixture of wa- ter and acetic acid, in analogy to a process described in Jerry March, 3rd edition, 1985, reaction 9-27, page 1087.

Compounds II (where Y is chlorine and R4 and R5 are hydrogen) may be prepared by the reaction sequence shown in Scheme 3 where the variable R'has the meanings given above and R3 is H, Cl, Br, I or CN: Scheme 3:

(VI) (Vil) (VIII) (IX) (II, Y = Cl) c) preparing a thiocyanato compound VII by thiocyanation of the aniline VI with thio- cyanogen, for example, in analogy to a process described in EP 945 449, in Jerry March, 3d edition, 1985, p. 476, in Neuere Methoden der organischen Chemie, Vol. 1, 237 (1944) or in J. L. Wood, Organic Reactions, vol. lil, 240 (1946); the thiocyanogen is usually prepared in situ by reacting, for example, sodium thiocy- anate with bromine in an inert solvent. Suitable solvents include alkanols such as methanol or ethanol or carboxylic acids such as acetic acid, propionic acid or isobutyric acid and mixtures thereof. Preferably, the inert solvent is methanol to which some sodium bromide may have been added for stabilization. d) conversion of the amino group in VII into a diazonium group by a conventional diazotation followed by conversion of the diazonium group into hydrogen, chlo- rine, bromine or iodine or cyano. Suitable nitrosating agents are nitrosonium tetrafluoroborate, nitrosyl chloride, nitrosyl sulfuric acid, alkyl nitrites such as t- butyl nitrite, or salts of nitrous acid such as sodium nitrite. The conversion of the resulting diazonium salt into the corresponding compound VIII where R3 = cyano, chlorine, bromine or iodine may be carried out by treatment of VII with a solution or suspension of a copper (l) salt, such as copper (l) cyanide, chloride, bromide or iodide or with a solution of an alkali metal salt (cf. , for example, Houben-Weyl, Methoden der organischen Chemie [Methods of Organic Chemistry], Georg Thieme Verlag Stuttgart, Vol. 5/4, 4'"edition 1960, p. 438 ff. ) The conversion of the resulting diazonium salt into the corresponding compound Vlil where R3 = H, for example, may be carried out by treatment with hypophosphorous acid, phos- phorous acid, sodium stannite or in non-aqueous media by treatment with tribu- tyltin hydride or (C2H5) 3SnH or with sodium borohydride (cf. , for example, Jerry March, 3rd edition, 1985,646f). e) reduction of the thiocyanate Vlil to the corresponding thiol compound IX by treatment with zinc in the presence of sulfuric acid or by treatment with sodium sulfide ; and subsequent f) oxidation of the thiol IX to obtain the sulfonylchloride 11 in analogy to step b) of scheme 2.

Furthermore, the benzenesulfonylchloride 11 (Y = Cl) may be prepared by the reaction sequence shown in Scheme 4 where the variables R', R3, R4 and R5 are as defined above.

Scheme 4: (XII) (XIII) (II, Y = Cl) (g) transformation of nitrotoluene X into the benzaldoxime compound XI, for example in analogy to a process described in WO 00/29394. The transformation of X into XI is e. g. achieved by reacting nitro compound X with an organic nitrite R-ONO, wherein R is alkyl in the presence of a base. Suitable nitrites are C2-C8-alkyl ni- trites such as n-butyl nitrite or (iso) amyl nitrite. Suitable bases are alkali metal alkoxide such as sodium methoxide, potassium methoxide or potassium tert- butoxide, alkali metal hydroxides such as NaOH or KOH or organo magnesium compounds such as Grignard reagents of the formula R'MgX (R'= alkyl, X = halogen). The reaction is usually carried out in an inert solvent, which preferably comprises a polar aprotic solvent. Suitable polar aprotic solvents include carbox- amides such as N, N-dialkylformamides, e. g. N, N-dimethylformamide, N, N- dialkylacetamides, e. g. N, N-dimethylacetamide or N-alkyllactames e. g. N- methylpyrrolidone or mixtures thereof or mixtures thereof with non-polar solvents such as alkanes, cycloalkanes and aromatic solvents e. g. toluene and xylenes.

When using sodium bases, 1-10 mol % of an alcohol may be added, if appropri- ate. The stoichiometric ratios are, for example, as follows: 1-4 equivalents of base, 1-2 equivalents of R-ONO; preferably 1.5-2. 5 equivalents of base and 1-1.3 equivalents of R-ONO; equally preferably: 1-2 equivalents of base and 1-1.3 equivalents of R-ONO. The reaction is usually carried out in the range from-60°C to room temperature, preferably-50°C to-20°C, in particular from-35°C to - 25°C.

(h) dehydration of the aldoxime Xi to the nitrile XII, for example by treatment with a dehydrating agent such as acetic anhydride, ethyl orthoformate and H+, (C6H5) 3P-CC14, trichloromethyl chloroformate, methyl (or ethyl) cyanoformate, trifluoromethane sulfonic anhydride in analogy to a procedure described in Jerry March, 4th edition, 1992,1038f ; (i) reduction of compound XII to the aniline XII1, for example by reacting the nitro compound XII with a metal, such as iron, zinc or tin or with SnCI2, under acidic conditions, with a complex hydride, such as lithium aluminium hydride and so- dium. The reduction may be carried out without dilution or in a solvent or diluent.

Suitable solvents are-depending on the reduction reagent chosen-for example water, alkanols, such as methanol, ethanol and isopropanol, or ethers, such as diethyl ether, methyl tert-butyl ether, dioxane, tetrahydrofuran and ethylene glycol dimethyl ether.

The nitro group in compound X ! ! may also be converted into an amino group by catalytic hydrogenation (see, for example, Houben Weyl, Vol. IV/1c, p. 506 ff or WO 00/29394). Catalysts being suitable are, for example, platinum or palladium catalysts, wherein the metal may be supported on an inert carrier such as acti- vated carbon, clays, celithe, silica, alumina, alkaline or earth alkaline carbonates etc. The metal content of the catalyst may vary from 1 to 20% by weight, based on the support. In general, from 0.001 to 1% by weight of platinum or palladium, based on the nitro compound Xll, preferably from 0.01 to 1% by weight of plati- num or palladium are used. The reaction is usually carried out either without a solvent or in an inert solvent or diluent. Suitable solvents or diluents include aro- matics such as benzene, toluene, xylenes, carboxamides such as N, N- dialkylformamides, e. g. N, N-dimethylformamide, N, N-dialkylacetamides, e. g. N, N- dimethylacetamide or N-alkyl lactames e. g. N-methylpyrrolidone, tetraalkylureas, such as tetramethylurea, tetrabutylurea, N, N'-dimethylpropylene urea and N, N'- dimethylethylene urea, alkanols such as methanol, ethanol, isopropanol, or n- butanol, ethers, such as diethyl ether, methyl ter-butyl ether, dioxane, tetrahydro- furan and ethylene glycol dimethyl ether, carboxylic acids such as acetic acid or propionic acid, carbonic acid ester such as ethyl acetate. The reaction tempera- ture is usually in the range from-20°C to 100 °C, preferably 0°C to 50°C. The hy- drogenation may be carried out under atmospheric hydrogen pressure or ele- vated hydrogen pressure.

(k) conversion of the amino group of compound XIII into the corresponding dia- zonium group followed by reacting the diazonium salt with sulfur dioxide in the presence of copper (II) chloride to afford the sulfonylchloride 11. The diazonium salt may be prepared as described in step d) of scheme 3. Preferably, sodium ni- trite is used as alkyl nitrite. In general, the sulfur dioxide is dissolved in glacial acetic acid.

The compounds of formula XIII may also be prepared according to methods described in WO 94/18980 using ortho-nitroanilines as precursors or WO 00/059868 using isatin precursors.

If individual compounds cannot be obtained via the above-described routes, they can be prepared by derivatization other compounds I or by customary modifications of the synthesis routes described.

The reaction mixtures are worked up in the customary manner, for example by mixing with water, separating the phases and, if appropriate, purifying the crude products by chromatography, for example on alumina or silica gel may be employed. Some of the intermediates and end products may be obtained in the form of colorless or pale brown viscous oils which are freed or purified form volatile components under reduced pres- sure and at moderately elevated temperature. If the intermediates and end products are obtained as solids, they may be purified by recrystallisation or digestion.

The compounds of the formula I are preferably used for controlling pests of the orders Homoptera and Thysanoptera.

The compounds of the formula I are also preferably used for controlling pests of the orders Hymenoptera.

The compounds of formula (I) or the pesticidal compositions comprising them may be used to protect growing plants and crops from attack or infestation by animal pests, especially insects or acaridae by contacting the plant/crop with a pesticidally effective amount of compounds of formula (I). The term"crop"refers both to growing and har- vested crops.

The animal pest, especially the insect, acaridae, plant and/or soil or water in which the plant is growing can be contacted with the present compound (s) I or composition (s) containing them by any application method known in the art. As such,"contacting"in- cludes both direct contact (applying the compounds/compositions directly on the animal pest, especially the insect and/or acaridae, and/or plant-typically to the foliage, stem or roots of the plant) and indirect contact (applying the compounds/compositions to the locus of the animal pest, especially the insect and/or acaridae, and/or plant).

Moreover, animal pests, especially insects or acaridae may be controlled by contacting the target pest, its food supply or its locus with a pesticidally effective amount of com- pounds of formula (I). As such, the application may be carried out before or after the infection of the locus, growing crops, or harvested crops by the pest.

"Locus"means a habitat, breeding ground, plant, seed, soil, area, material or environ- ment in which a pest or parasite is growing or may grow.

Effective amounts suitable for use in the method of invention may vary depending upon the particular formula I compound, target pest, method of application, application tim- ing, weather conditions, animal pest habitat, especially insect, or acarid habitat, or the like. In general, for use in treating crop plants, the rate of application of the compounds I and/or compositions according to this invention may be in the range of about 0.1 g to about 4000 g per hectare, desirably from about 25 g to about 600 g per hectare, more desirably from about 50 g to about 500 g per hectare. For use in treating seeds, the typical rate of application is of from about 1 g to about 500 g per kilogram of seeds, desirably from about 2 g to about 300 g per kilogram of seeds, more desirably from about 10 g to about 200 g per kilogram of seeds. Customary application rates in the protection of materials are, for example, from about 0.001 g to about 2000 g, desirably

from about 0.005 g to about 1000 g, of active compound per cubic meter of treated material.

The compounds I or the pesticidal compositions comprising them can be used, for ex- ample in the form of solutions, emulsions, microemulsions, suspensions, flowable con- centrates, dusts, powders, pastes and granules. The use form depends on the particu- lar purpose; in any case, it should guarantee a fine and uniform distribution of the com- pound according to the invention.

The pesticidal composition for combating animal pests, especially insects and/or acari- dae contains such an amount of at least one compound of the general formula I or an agricultural useful salt of I and auxiliaries which are usually used in formulating pesti- cidal composition.

The formulations are prepared in a known manner, e. g. by extending the active ingre- dient with solvents and/or carriers, if desired using emulsifiers and dispersants, it also being possible to use other organic solvents as auxiliary solvents if water is used as the diluent. Auxiliaries which are suitable are essentially : solvents such as aromatics (e. g. xylene), chlorinated aromatics (e. g. chlorobenzenes), paraffins (e. g. mineral oil frac- tions), alcohols (e. g. methanol, butanol), ketones (e. g. cyclohexanone), amines (e. g. ethanolamine, dimethylformamide) and water; carriers such as ground natural minerals (e. g. kaolins, clays, talc, chalk) and ground synthetic minerals (e. g. highly-disperse silica, silicates) ; emulsifiers such as non-ionic and anionic emulsifiers (e. g. poly- oxyethylene fatty alcohol ethers, alkylsulfonates and arylsulfonates) and dispersants such as lignin-sulfite waste liquors and methylcellulose.

Suitable surfactants are alkali metal, alkaline earth metal and ammonium salts of ligno- sulfonic acid, naphthalenesulfonic acid, phenolsulfonic acid, dibutylnaphthalenesulfonic acid, alkylarylsulfonates, alkyl sulfates, alkylsulfonates, fatty alcohol sulfates and fatty acids and their alkali metal and alkaline earth metal salts, salts of sulfate fatty alcohol glycol ether, condensates of sulfonate naphthalene and naphthalene derivatives with formaldehyde, condensates of naphthalene or of napthalenesulfonic acid with phenol or formaldehyde, polyoxyethylene octylphenyl ether, ethoxylated isooctylphenol, octyl- phenol, nonylphenol, alkylphenol polyglycol ethers, tributylphenyl polyglycol ethers, alkylaryl polyether alcohols, isotridecyl alcohol, fatty alcohol/ethylene oxide conden- sates, ethoxylated castor oil, polyoxyethylene alkyl ethers, ethoxylated polyoxypropyl- ene, lauryl alcohol polyglycol ether acetal, sorbitol esters, lignin-sulfite waste liquors and methylcellulose.

Substances which are suitable for the preparation of directly sprayable solutions, emul- sions, pastes or oil dispersions are mineral oil fractions of medium to high boiling point, such as kerosene or diesel oil, furthermore coal tar oils and oils of vegetable or animal origin, aliphatic, cyclic and aromatic hydrocarbons, e. g. benzene, toluene, xylene, par- affin, tetrahydronaphthalene, alkylated naphthalenes or their derivatives, methanol,

ethanol, propanol, butanol, chloroform, carbon tetrachloride, cyclohexanol, cyclohexa- none, chlorobenzene, isophorone, strongly polar solvents, e. g. dimethylformamide, dimethyl sulfoxide, N-methylpyrrolidone and water.

Powders, materials for scattering and dusts can be prepared by mixing or concomi- tantly grinding the active substances with a solid carrier.

Granules, e. g. coated granules, compacted granules, impregnated granules and ho- mogeneous granules, can be prepared by binding the active ingredients to solid carri- ers. Examples of solid carriers are mineral earths, such as silicas, silica gels, silicates, talc, kaolin, attaclay, limestone, lime, chalk, bole, loess, clay, dolomite, diatomaceous earth, calcium sulfate, magnesium sulfate, magnesium oxide, ground synthetic materi- als, fertilizers, e. g. ammonium sulfate, ammonium phosphate, ammonium nitrate, ureas, and products of vegetable origin, such as cereal meal, tree bark meal, wood meal and nutshell meal, cellulose powders and other solid carriers.

Such formulations or compositions of the present invention include a formula I com- pound of this invention (or combinations thereof) admixed with one or more agronomi- cally acceptable inert, solid or liquid carriers. Those compositions contain a pesticidally effective amount of said compound or compounds, which amount may vary depending upon the particular compound, target pest, and method of use.

In general, the formulations comprise of from 0.01 to 95% by weight, preferably from 0.1 to 90% by weight, of the active ingredient. The active ingredients are employed in a purity of from 90% to 100%, preferably 95% to 100% (according to NMR spectrum).

The following are exemplary formulations : I. 5 parts by weight of a compound according to the invention are mixed intimately with 95 parts by weight of finely divided kaolin. This gives a dust which comprises 5% by weight of the active ingredient.

II. 30 parts by weight of a compound according to the invention are mixed intimately with a mixture of 92 parts by weight of pulverulent silica gel and 8 parts by weight of paraffin oil which had been sprayed onto the surface of this silica gel.

This gives a formulation of the active ingredient with good adhesion properties (comprises 23% by weight of active ingredient).

III. 10 parts by weight of a compound according to the invention are dissolved in a mixture composed of 90 parts by weight of xylene, 6 parts by weight of the ad- duct of 8 to 10 mol of ethylene oxide and 1 mol of oleic acid N- monoethanolamide, 2 parts by weight of calcium dodecylbenzenesulfonate and 2 parts by weight of the adduct of 40 mol of ethylene oxide and 1 mol of castor oil

(comprises 9% by weight of active ingredient).

VI. 90 parts by weight of a compound according to the invention are mixed with 10 parts by weight of N-methyl-a-pyrrolidone, which gives a solution which is suit- able for use in the form of microdrops (comprises 90% by weight of active ingre- dient).

Vil. 20 parts by weight of a compound according to the invention are dissolved in a mixture composed of 40 parts by weight of cyclohexanone, 30 parts by weight of isobutanol, 20 parts by weight of the adduct of 7 mol of ethylene oxide and 1 mol of isooctylphenol and 10 parts by weight of the adduct of 40 mol of ethylene ox- ide and 1 mol of castor oil. Pouring the solution into 100,000 parts by weight of water and finely distributing it therein gives an aqueous dispersion which com- prises 0.02% by weight of the active ingredient.

VIII. 20 parts by weight of a compound according to the invention are mixed thor- oughly with 3 parts by weight of sodium diisobutylnaphthalene-a-sulfonate, 17 parts by weight of the sodium salt of a lignosulfonic acid from a sulfite waste liq- uor and 60 parts by weight of pulverulent silica gel, and the mixture is ground in a hammer mill. Finely distributing the mixture in 20,000 parts by weight of water gives a spray mixture which comprises 0. 1% by weight of the active ingredient.

The active ingredients can be used as such, in the form of their formulations or the use forms prepared therefrom, e. g. in the form of directly sprayable solutions, powders, suspensions or dispersions, emulsions, oil dispersions, pastes, dusts, materials for spreading, or granules, by means of spraying, atomizing, dusting, scattering or pouring.

The use forms depend entirely on the intended purposes; in any case, this is intended to guarantee the finest possible distribution of the active ingredients according to the invention.

Aqueous use forms can be prepared from emulsion concentrates, pastes or wettable powders (sprayable powders, oil dispersions) by adding water. To prepare emulsions,

pastes or oil dispersions, the substances as such or dissolved in an oil or solvent, can be homogenized in water by means of wetter, tackifier, dispersant or emulsifier. Alter- naively, it is possible to prepare concentrates composed of active substance, wetter, tackifier, dispersant or emulsifier and, if appropriate, solvent or oil, and such concen- trates are suitable for dilution with water.

The active ingredient concentrations in the ready-to-use products can be varied within substantial ranges. In general, they are from 0.0001 to 10%, preferably from 0.01 to 1%.

The active ingredients may also be used successfully in the ultra-low-volume process (ULV), it being possible to apply formulations comprising over 95% by weight of active ingredient, or even the active ingredient without additives.

Compositions to be used according to this invention may also contain other active ingredients, for example other pesticides, insecticides, herbicides, fungicides, other pesticides, or bactericides, fertilizers such as ammonium nitrate, urea, potash, and superphosphate, phytotoxicants and plant growth regulators, safeners and nematicides. These additional ingredients may be used sequentially or in combination with the above-described compositions, if appropriate also added only immediately prior to use (tank mix). For example, the plant (s) may be sprayed with a composition of this invention either before or after being treated with other active ingredients.

These agents can be admixed with the agents used according to the invention in a weight ratio of 1: 10 to 10: 1. Mixing the compounds I or the compositions comprising them in the use form as pesticides with other pesticides frequently results in a broader pesticidal spectrum of action.

The reaction mixture was stirred at room temperatures for 10 minutes and then a solution of 6.4 g (92 mmol) of sodium nitrite in 20 ml of water was added dropwise at 5-10°C. The reac- tion mixture was stirred at 0°C for one hour to obtain the diazonium salt. In a separate stirred flask, a saturated solution of sulfur dioxide in glacial acetic acid was prepared at 10°C and a solution of 5.5 g of copper ( ! t) chloride in 11 ml of water was added. The reaction mixture of the diazonium salt which had been prepared beforehand was then added dropwise to the solution of the copper salt. The resulting mixture was stirred at room temperature for additional 45 minutes. Then the reaction mixture was poured into ice-cooled water and the aqueous phase was extracted three times with dichloro- methane. The combined organic layers were dried over a drying agent and filtered. The filtrate was concentrated in vacuo to afford 16.4 g (87% of the theory) of the title com- pound having a melting point of 75-77°C.

1.2 : n-Propyl- (2-cyano-3-methyl-phenyl) sulfonamide

The reaction mixture was stirred at room tem- perature for 3 hours before water was added. The aqueous phase was acidified with hydrochloric acid (10% strength by weight, aqueous solution) to pH = 3 and then ex- tracted three times with dichloromethane. The combined organic extracts were dried over sodium sulfate and filtered. The filtrate was concentrated in vacuo to afford 850 mg (85% of theory) of the title compound having a melting point of 74-77°C.

The mixture was then refluxed for 5 hours under stirring. The completion of the reaction was monitored by TLC. Additional 25 g of so- dium methoxide in 35 ml methanol were added and the reaction mixture was refluxed for additional 4 hours while stirring. The reaction mixture was concentrated under re- duced pressure, the resulting residue was triturated with water, sucked off and the ob- tained solids were dissolved in ethyl acetate. The resulting solution was concentrated in vacuo. The obtained residue was triturated with petroleum ether and sucked off to afford 48 g (63% of theory) of a brownish solid having a melting point of 143-146°C.

2.2 : 2-Cyano-3-methoxy-phenylsulfonylchloride 10 g of concentrated hydrochloric acid were slowly added to a solution of 4.0 (27 mmol) of 2-amino-6-methoxy-benzonitrile in 32 ml of glacial acetic acid at room temperature while stirring. The mixture was stirred at room temperatures for 10 minutes. Then a solution of 1.9 g (27.3 mmol) sodium nitrite in 5 mi of water was added at 5-10°C and the reaction mixture was stirred at 0°C for 1 hour to obtain the diazonium salt. In a separate flask, a saturated solution of sulfur dioxide in 68 ml of glacial acetic acid was prepared at room temperature and a solution of 1.7 g of copper (li) chloride in 4 mi of water was added. The reaction mixture of the diazonium salt which had been prepared beforehand was then quickly added to the solution of the copper salt. The resulting mixture was stirred at room temperature for additional 2.5 hours. The reaction mixture was then poured into ice-cooled water. The aqueous layer was extracted three times with dichloromethane. The combined organic extracts were dried over a drying agent and filtered off with suction.

A solution of 1.25 g (5.4 mmol) of 2-cyano-3-methoxy-phenylsulfonylchloride in 30 ml of tetrahydrofuran was added to a solution of 960 mg (12 mmol) of an aqueous solution of methylamine (40% by weight) in 20 ml of tetrahydrofuran at room temperature. The reaction mixture was stirred at room temperature for 30 minutes before water was added. The aqueous phase was acidified to pH = 3 using hydrochloric acid (10% strength by weight, aqueous solution). The aqueous phase was then extracted three times with dichloromethane. The combined organic extracts were dried over sodium sulfate and filtered. The filtrate was concentrated in vacuo and the resulting residue was triturated with methyl tert-butyl ether to afford 0.28 g (23% of theory) of the title compound having a melting point of 121-128 °C.

The mixture was stirred for 10 minutes, and then a solution of 11 g (160 mmol) of sodium nitrite in 23 ml of water was added dropwise at 5-10 °C to obtain the diazonium salt. In a separate flask, a solu- tion of 16 g of copper (l) chloride in 50 ml of concentrated hydrochloric acid was pre- pared. The reaction mixture of the diazonium salt which had been prepared before- hand was then quickly added dropwise to the solution of the copper salt. The resulting reaction mixture was stirred at room temperature for 24 hours. The reaction mixture was then poured into ice-cooled water and the aqueous phase was extracted three times with dichloromethane. The combined organic layers were dried, filtered and then evaporated. The resulting crude product was purified by column chromatography on silica gel (eluent : toluene/ethyl acetate) to yield 14.3 g (43% of theory) of the title com- pound having a melting point of 78-80°C.

The resulting yellow solution was stirred at room temperature for 2 days. The mixture was then diluted with water and extracted with methyl ter-butyl ether. The aqueous phase was adjusted to pH 7 by addition of concentrated hydrochloric acid and then extracted with dichloromethane. The aqueous phase was subsequently adjusted to pH 1 by addition of concentrated hydrochloric acid and then extracted with dichloro- methane. The organic layer was dried, filtered and then concentrated. The obtained residue was suspended in a mixture of 20 ml of glacial acetic acid, 5 ml of dichloro- methane and 18 mi of water and a stream of chlorine gas was then introduced at 25-

45°C over a period of 3 hours. The reaction mixture was diluted with dichloromethane and the organic phase was washed with ice-cooled water. Drying of the organic phase over sodium sulfate was followed by filtration and concentration of the solution to yield 1.3 g (36% of theory) of the title compound having a melting point of 69-72°C.

3.3 : Ethyl- (4-chloro-2-cyano-3-methyl-phenyl) sulfonamide An aqueous solution of 770 mg (12 mmol) of ethylamin (70% by weight) in 20 ml of tetrahydrofuran was initially charged, and a solution of 1.3 g (5.2 mmol) of 4-chloro-2- cyano-3-methylphenylsulfonylchloride from 3.2. in 10 ml of tetrahydrofuran was added dropwise at room temperature. The reaction mixture was stirred at room temperature for 2 hours, diluted with water and adjusted to pH 3 by addition of hydrochloric acid (10% strength by weight, aqueous solution). The aqueous phase was extracted three times with dichloromethane. The combined organic layers were dried over sodium sul- fate, filtered and then evaporated to dryness in vacuo to obtain 0.5 g (28% of theory) of a brown solid having a melting point of 85-90°C.

Examples of action against pests The action of the compounds of the formula I against pests was demonstrated by the following experiments: Green Peach Aphid (Myzus persicae)

The active compounds were formulated in 50: 50 acetone: water and 100 ppm Kine- tic@ surfactant.

Pepper plants in the 2"d leaf-pair stage (variety'California Wonder') were infested with approximately 40 laboratory-reared aphids by placing infested leaf sections on top of the test plants. The leaf sections were removed after 24 hr. The leaves of the intact plants were dipped into gradient solutions of the test compound and allowed to dry.

Test plants were maintained under fluorescent light (24 hour photoperiod) at about 25°C and 20-40% relative humidity. Aphid mortality on the treated plants, relative to mortality on check plants, was determined after 5 days.

In this test, compounds nos. 1,2, 3,5, 12,23, 29,30, 31,33, 37,38, 39,40, 41,42, 43, 45,46, 47,48, 49,50, 52,53, 54, and 55 at 300 ppm showed over 85% mortality in comparison with untreated controls.

Cotton Aphid (Aphis gossypii) The active compounds were formulated in 50: 50 acetone: water and 100 ppm Ki- netic@ surfactant.

Cotton plants in the cotyledon stage (variety'Delta Pine', one plant per pot) were in- fested by placing a heavily infested leaf from the main colony on top of each cotyle- dons. The aphids were allowed to transfer to the host plant overnight, and the leaf used to transfer the aphids were removed. The cotyledons were dipped in the test solution and allowed to dry. After 5 days, mortality counts were made.

In this test, compounds nos. 2,3, 5,6, 8,10, 12,13, 14,15, 16,18, 19,20, 21,22, 23, 24,25, 27,28, 29, 30,31, 32,35, 36,37, 38,39, 40,41, 42,43, 44,45, 46,47, 48,49, 50,51, 52,53, 54, and 55 at 300 ppm showed over 85% mortality in comparison with untreated controls.

Bean Aphid (Aphis fabae) The active compounds were formulated in 50: 50 acetone: water and 100 ppm Ki- netic@ surfactant.

Nasturtium plants grown in Metro mix in the lst leaf-pair stage (variety'Mixed Jewel') were infested with approximately 2-30 laboratory-reared aphids by placing infested cut plants on top of the test plants. The cut plants were removed after 24 hr. Each plant was dipped into the test solution to provide complete coverage of the foliage, stem, protruding seed surface and surrounding cube surface and allowed to dry in the fume hood. The treated plants were kept at about 25°C with continuous fluorescent light.

Aphid mortality is determined after 3 days.

In this test, compounds nos. 30,38, 5,6, 7,8, 23,29, 32,33, 34,35, 40,41, 42, and 45 at 300 ppm showed over 85% mortality in comparison with untreated controls.

Silverleaf whitefly (Bemisia argentifoli/) The active compounds were formulated in 50: 50 acetone: water and 100 ppm Ki- acetic0 surfactant.

Selected cotton plants were grown to the cotyledon state (one plant per pot). The coty- ledons were dipped into the test solution to provide complete coverage of the foliage and placed in a well-vented area to dry. Each pot with treated seedling was placed in a plastic cup and 10 to 12 whitefly adults (approximately 3-5 day old) were introduced.

The insects were collected using an aspirator and an 0.6 cm, non-toxic Tygon (E) tubing (R-3603) connected to a barrier pipette tip. The tip, containing the collected insects, was then gently inserted into the soil containing the treated plant, allowing insects to crawl out of the tip to reach the foliage for feeding. The cups were covered with a reus- able screened lid (150 micron mesh polyester screen PeCap from Tetko Inc). Test plants were maintained in the holding room at about 25°C and 20-40% humidity for 3 days avoiding direct exposure to the fluorescent light (24 photoperiod) to prevent trap- ping of heat inside the cup. Mortality was assessed 3 days after treatment of the plants.

In this test, compounds no. 5 and 42 at 300 ppm showed over 70% mortality compared to untreated controls.

2-spotted Spider Mite (Tetranychus urticae, OP-resistant strain) Sieva lima bean plants (variety'Henderson') with primary leaves expanded to 7-12 cm were infested by placing on each a small piece from an infested leaf (with about 100 mites) taken from the main colony. This was done at about 2 hours before treatment to allow the mites to move over to the test plant to lay eggs. The piece of leaf used to transfer the mites was removed. The newly-infested plants were dipped in the test solu- tion and allowed to dry. The test plants were kept under fluorescent light (24 hour pho- toperiod) at about 25°C and 20-40% relative humidity. After 5 days, one leaf was re- moved and mortality counts were made.

In this test, compounds nos. 8 and 30 at 300 ppm showed over 75% mortality com- pared to untreated controls.

Florida Carpenter Ant (Camponotus floridanus) The tests were conducted in petri dishes. Ants were given a water source and then were starved of a food source for 24 hours. Baits were prepared with 20 % honey/water solution. A solution of the active ingredient in acetone was added to reach a concentra- tion of the active ingredient of 1 % by weight (w/w). 0.2 mi of the active ingredient con-

taining honey/water solution, placed in a cap, was added to each dish. The dishes were covered and maintained at a water temperature of 22°C. The ants were observed for mortality daily. Mortality was determined after 10 days.

In these tests, compounds nos. 66,78 and 79 showed over 85% mortality compared to untreated controls.

Argentine Ants (Linepithema humile) a) The tests were conducted in petri dishes. Ants were given a water source and then were starved of a food source for 24 hours. Baits were prepared with 20% honey/water solution. A solution of the active ingredient in acetone was added to reach a concentration of the active ingredient of 1% by weight (w/w). 0.2 ml of the active ingredient containing honey/water solution, placed in a cap, was added to each dish. The dishes were covered and maintained at a water temperature of 22°C. The ants were observed for mortality daily. Mortality was determined after 10 days.

In these tests, compounds nos. 66,78 and 79 showed 100% mortality compared to untreated controls. b) The tests were conducted as in example a). The following compounds I and 11 ac- cording to EP 33984 were used as comparative examples. The ants were observed for mortality after 6 days. The results are shown in Table 3.
