Silver-Catalyzed Reaction of Chlorosilanes with Grignard Reagents for the Synthesis of Tetraorganosilanes

摘要

Nucleophilic substitution reaction of chlorosilanes with organometallic reagents is a fundamental method for forming carbon-silicon bonds. The reactions of chlorotriorganosilanes with organomagnesium reagents often require prolonged reaction times and high temperatures, and result in moderate yields of tetraorganosilanes. During the course of our recent studies on the silver catalysis, we have found that silver salts can catalyze the reactions of chlorotriorganosilanes with organomagnesium reagents to yield a variety of tetraorganosilanes efficiently.
