ABSTRACT
The generalized structure of an organosilane is RIISiX(4 - n " where X is an electron-withdrawing group, typically halide. In the simplest and earliest examples of the reaction chemistry, silicon tetrachloride was substituted by addition of Grignard reagents, such as ethylmagnesium bromide and phenylmagnesium chloride [ 1 ,3]. In addition, Grignard reagents substitute alkoxides (OR), siloxanes (O-Si), and nitriles (eN).
