Acceleration of the Substitution of Silanes with Grignard Reagents by Using either LiCl or YCl₃/MeLi

Abstract

Getting up to speed: Both LiCl and the YCl3/MeLi catalyst system have an acceleration effect upon the substitution of silanes using Grignard reagents (see scheme). The method provides access to benzyl-, allyl-, and arylsilanes in good yields from the starting silanes.
