Abstract

Disclosed herein is a process for the hydrosilylation 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 silyl hydride to react with the compound containing at least one unsaturated group to produce a hydrosilylation product.
