Document Type and Number:

Japanese Patent JP4074346

Kind Code:

B2

Abstract:

The invention relates to a method for producing organo alkali-metal compounds by reacting metal lithium, sodium or potassium with organic compounds containing at least one acidic CH bond in a solvent. The inventive method is characterized in that the reaction is carried out in the presence of a hydrogen acceptor, wherein 0.5 to 5 moles of the hydrogen acceptor are used per mole of acid hydrogen, which hydrogen can be replaced by lithium, sodium or potassium, whereby 1 to 3, moles of lithium, sodium or potassium are used per mole of acid hydrogen and the acid CH bond has a pKa value of 10 to 30. Cyclopentadiene, indene, fluorene and substitution products thereof, or monosubstituted alkynes or methane substitution products, are preferred CH acid organic compounds. Hydrocarbons used as hydrogen acceptors include these with at least one CC double bond in conjugation with either another CC double bond or with a monocyclic aryl radical.
