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 compound and (d) a cyclodiene, with the provisos that (i) when the unsaturated compound is a terminal alkyne, the silyl hydride is other than a halosilane, and (ii) when the platinum compound is a Pt(II)-based compound, the ratio of total moles of cyclodiene to moles of platinum is less than 3:1.
