Abstract
A composition and method can be used in the preparation of various siloxanes. The composition and method employ a fluorinated triarylborane Lewis acid, a hydrocarbonoxy-functional organosilicon compound, and a silyl hydride. The fluorinated triarylborane Lewis acid catalyzes reaction of a hydrocarbonoxy moiety (from the organosilicon compound) and a silicon-bonded hydrogen atom (from the silyl hydride) to form a siloxane bond.
