Abstract

Disclosed herein are cobalt complexes containing pyridine di-imine ligands and chelating alkenyl-modified silyl ligands, and their use as hydrosilylation and/or dehydrogenative silylation and crosslinking catalysts. The cobalt complexes also exhibit adequate air stability for handling and manipulation.
