Abstract
A process for the hydrosilylation of an unsaturated compound comprising reacting (a) a silyl hydride with (b) an unsaturated compound in the presence of (c) a platinum based hydrosilylation catalyst comprising a platinum-diene complex with chelating anions. The use of the present catalysts in the process provides silylated products in good yields and allows for using lower platinum loadings than conventional catalysts, reduced cycle times, and may reduce yellowing in the product.
