Title:
IN-SITU ACTIVATION OF METAL COMPLEXES USED AS HYDROSILYLATION CATALYSTS
Document Type and Number:
WIPO Patent Application WO/2012/071358
Kind Code:
A3
Abstract:
Disclosed herein is a process for the hydrasilylation of a composition containing a silyl hydride and a compound containing at least one unsaturated group, the process comprising contacting a non-previous metal based complex as a catalyst precursor with an activator being a reducing agent shortly before, simultaneously or after contacting the complex with the composition, to cause the siiyl hydride to react with the compound containing at least one unsaturated group to produce a hydrosilylation product.
