Abstract: Disclosed herein is the use of manganese, iron, cobalt, or nickel complexes containing tridentate pyridine di-imine ligands as hydrosilylation catalysts. These complexes are effective for efficiently catalyzing hydrosilylation reactions, as well as offering improved selectivity and yield over existing catalyst systems.

Abstract: A process for producing a silylated product comprises reacting a mixture comprising (a) an unsaturated compound containing at least one unsaturated functional group, (b) a silyl hydride containing at least one silylhydride functional group, and (c) a catalyst, optionally in the presence of a solvent, to produce a dehydrogenative silylated product, a hydrosilylated product, or a combination of a dehydrogenative silylated product and a hydrosilylated product, wherein the catalyst is chosen from a pyridine diimine cobalt dicarboxylate complex or a cobalt carboxylate compound, and the process is conducted without pre-activating the catalyst via a reducing agent and/or without an initiator or promoter compound. The present catalysts have been found to be active in the presence of the silyl hydride employed in the silylation reaction.
