PLATINUM CATALYZED HYDROSILYLATION REACTIONS UTILIZING CYCLODIENE ADDITIVES

摘要

A process and composition 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 compound and (d) a cyclodiene, with the proviso that when the unsaturated compound is a terminal alkyne, the silyl hydride is other than a halosilane. The process and composition optionally comprise an inhibitor (e). The process and composition may be employed to form a variety of hydrosilylation products.
