A composition includes a silyl hydride (having at least one silicon-bonded hydrogen atom per molecule) and a fluorinated triarylborane Lewis acid. In the method, the Lewis acid catalyzes reaction of silicon bonded hydrogen atoms from the silyl hydride and water, thereby forming a siloxane bond in the resulting product. The composition and method can be used to form siloxane intermediates and cured networks.

Composition and method for silyl hydride reaction catalyzed by fluorinated arylborane Lewis acids

A polyfunctional organohydrogensiloxane is prepared using a fluorinated triarylborane Lewis acid as catalyst. The polyfunctional organohydrogensiloxane may be formulated into release coating compositions. Alternatively, the polyfunctional organohydrogensiloxane may be further functionalized with a curable group to form a clustered functional organosiloxane. The clustered functional organosiloxane may be formulated into thermal radical cure adhesive compositions.

Methods for making polyfunctional organosiloxanes and compositions containing same

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.
