Title:
PROCESS FOR THE PREPARATION OF BENZYL-METAL COMPOUNDS AND PROCESS FOR THE PREPARATION OF 4-PHENYL-1-BUTENES BY THE USE OF THE SAME
Document Type and Number:
WIPO Patent Application WO/1997/045433
Kind Code:
A1
Abstract:
A process for the preparation of benzyl-metal compounds of general formula (2) wherein M is an alkali metal by reacting a phenyl-metal compound of general formula (1) wherein M is an alkali metal with toluene in the presence of a catalytic amount of an amine, which permits the industrially advantage preparation of the objective compounds in a high yield; and a process for the preparation of 4-phenyl-1-butenes by reacting a benzyl-metal compound prepared by the above process with an allyl halide.
