Abstract
A series of nitrogen phosphine ligands were synthesized, and the hydrosilylation reaction of alkenes catalyzed using MCl2 in the presence of these ligands was investigated. FeCl2/1(N1, N1, N2, N2‐Tetrakis[(diphenylphosphino)methyl]ethane‐1,2‐diamine) showed low catalytic activity. MnCl2/1, CrCl3/1 and NiCl2/1 showed some catalytic activity. The CoCl2/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. CoCl2/1 showed the highest catalytic activity (~ >99.9% conversion of 1‐octene). Additionally, no α‐adduct, dehydrogenative silylation product and octane were detected.
