Document Type and Number:
Japanese Patent JPH05202066
Kind Code:
A
Abstract:
PURPOSE: To provide a producing method of a pure alkyl lithium compd. with high yield.
CONSTITUTION: In the alkylation method of alkali metals with alkylhalides, the alkylation reaction is carried out in a hydrocarbon solvent in the presence of a catalyst expressed by (RR1R2Ma)yA(R3)x. In the formula, R, R1 and R2 are each selected from H, halogen, alkyl, alkenyl, cycloalkyl and aryl; R3 is selected from aryl, 4 to 6-membered heterocyclic carbon-contg. ring, hydroxyalkyl, alkoxyalkyl, monoalkylaminoalkyl and dialkylaminoalkyl; Ma is selected from silicon, carbon, germanium and tin; A is selected from oxygen, sulfur, nitrogen and phosphorus; (x) and (y) are independently 0 to 3.
