A series of nitrogen phosphine ligands were synthesized, and the hydrosilylation reaction of alkenes catalyzed using MCl 2 in the presence of these ligands was investigated. FeCl 2 / 1 ( N 1 , N 1 , N 2 , N 2 ‐Tetrakis[(diphenylphosphino)methyl]ethane‐1,2‐diamine) showed low catalytic activity. MnCl 2 / 1, CrCl 3 / 1 and NiCl 2 / 1 showed some catalytic activity. The CoCl 2 / N , P ‐ligand catalyst system showed high activity as well as excellent selectivity (The selectivity of the β ‐adduct was ~100%.) in the hydrosilylation reaction. CoCl 2 / 1 showed the highest catalytic activity (~ >99.9% conversion of 1‐octene). Additionally, no α‐adduct, dehydrogenative silylation product and octane were detected.
