Abstract
A new silicone condensation reaction, the condensation between an alkoxy silane or siloxane and an organo-hydrosilane or siloxane and catalysts therefore is described and claimed.
Claims8
A process for forming a silicon to oxygen bond in a compound comprising:
- a) selecting a compound comprising both a hydrogen atom directly bonded to a first silicon atom and an alkoxy group bonded to a second silicon atom in said compound and
- b) reacting the hydrosilane moiety with the silicon-alkoxy group, in the presence of
- c) a Lewis acid catalyst thereby forming a silicon to oxygen bond.
