Document Type and Number:
Japanese Patent JP2680906
Kind Code:
B2
Abstract:
The present invention relates to a process for synthesizing N-chlorothio-sulfonamides of the formula: comprising reacting a N,N min -dithiobis(sulfonamide) of the formula: with chlorine gas or sulfuryl chloride in the presence of a liquid solvent comprising a N-chlorothio-sulfonamide of formula I, wherein R<1> and R<2> are independently selected from the group consisting of alkyl radicals having from about 1 to about 20 carbon atoms, aralkyl radicals having 7 to 20 carbon atoms, cycloalkyl radicals having from about 5 to about 20 carbon atoms, phenyl radicals, alkaryl radicals having from about 7 to 20 carbon atoms, and haloaryl radicals having about 6 to about 10 carbon atoms and where R<1> is also selected from radicals having the formula: wherein R<3> and R<4> are individually selected from said alkyl, aralkyl, cycloalkyl, phenyl, alkaryl and haloaryl radicals and wherein R<3> and R<4> can be joined together to represent radicals selected from &lparstr& CH2 &rparstr& n, where n is an integer of 4 to 7 and &lparstr& CH2 &rparstr& @O-(CH2 &rparstr& 2.
