Abstract
The present invention is a process for the disproportionation of arylsilanes using a phenylborane as a catalyst. The process uses sodium borohydride to activate the phenylborane catalyst, thereby reducing the induction time associated with the use of the phenylborane catalyst. The present process is especially useful for the disproportionation of phenyldichlorosilane to diphenyldichlorosilane and dichlorosilane.
