s Carboxylate-Functionalized P, N-Ligated Cobalt Catalysts for Alkene Hydrosilylation

A series of N, P-ligands bearing carboxyl groups have been synthesized. These have been applied in conjunction with cobalt naphthenate in a facile, economic, and efficient method for the catalytic hydrosilylation of alkenes. In the presence of KO^tBu as an additive, the reaction time and activation energy are greatly reduced.
