Abstract

A 86:14 isomeric mixture of 3,4-[3'-(dichlorosilyl)isopropyl]benzo-1,1-dichloro-1-silacyclopentene and 3,4-[2'-(dichlorosilyl)isopropyl]benzo-1,1-dichloro-1-silacyclopentene was prepared by the regioselective Friedel-Crafts reaction of allyldichlorosilane with 3,4-benzo-1,1-dichloro-1-silacyclopentene catalyzed by Lewis acid AlCl3. The structure of the products was confirmed by methylation with methylmagnesium bromide and by methoxylation with trimethylorthoformate.
