ABSTRACT:
Dimethylchlorosilane and a triorganochlorosilane of the formula: R.sup.1 R.sup.2 R.sup.3 SiCl wherein R.sup.1, R.sup.2, and R.sup.3 are independently selected from monovalent hydrocarbon groups are concurrently prepared by reacting dimethyldichlorosilane with a SiH bond-containing silane compound of the formula: R.sup.1 R.sup.2 R.sup.3 SiH in the presence of a Lewis acid catalyst. The method is especially effective for concomitant preparation of dimethylchlorosilane and trimethylchlorosilane or t-butyldimethylchlorosilane in an inexpensive, simple, safe manner and in high yields.
