Reactions of methylchlorodisilanes with Grignard reagents

Abstract

Reactions of Cl2MeSiSiMeCl2 with RMgCl make it possible to obtain and isolate pure disilanes containing a smaller number of functional groups, namely, RMeClSiSiMeCl2 (R = Ph), RMeClSiSiMeRCl (R = Pri, Ph), and R2MeSiSiMeRCl (R = Bui). The reaction of Cl2MeSiSiMeCl2 with BunMgCl is the least selective. The chlorides obtained were reduced with LiAlH4 into the corresponding hydrides.
