In a reaction which has broad implications for many ostensibly homogeneous metal-catalyzed reduction processes, it is shown that platinum-catalyzed hydrosilylation proceeds with formation of platinum colloids. The reaction of COD PtCl/sub 2/ with (EtO/sub 2/)/sub 3/SiH demonstrated that colloid formation is the key step in hydrosilylation. Colloids are generated from the reaction of Pt(COD)/sub 2/ and CODPtCl/sub 2/ with hydrosilanes and analyzed by light scattering, TEM, and ESCA.
