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

A method for forming product with a siloxane bond, the method comprising:

• 1. Combining starting materials comprising
• A) a fluorinated triarylborane Lewis acid selected from the group consisting of:
• A1) tris(3,5-bis(trifluoromethyl)phenyl)borane THF adduct;
• A2) bis(3,5-bis(trifluoromethyl)phenyl)(4-trifluoromethylphenyl)borane THF adduct;
• A3) bis(3,5-bis(trifluoromethyl)phenyl)(2,4,6-trifluorophenyl)borane THF adduct;
• A4) bis(3,5-bis(trifluoromethyl)phenyl)(2,6-difluorophenyl)borane THF adduct;
• A5) bis(3,5-bis(trifluoromethyl)phenyl)(2,5-bis(trifluoromethyl)phenyl)borane;
• A6) (3,5-bis(trifluoromethyl)phenyl)bis(2,5-bis(trifluoromethyl)phenyl)borane;
• A7) bis(3,5-bis(trifluoromethyl)phenyl)(2,3,5,6-tetrafluoro-4-trifluoromethylphenyl)borane THF adduct;
• and
• A8) a combination of two or more of A1) to A7);
• B) a silyl hydride having at least one silicon-bonded hydrogen atom per molecule, and
• C) water;
• thereby reacting the silicon-bonded hydrogen atom to form the siloxane bond and a by-product comprising hydrogen.
