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.
