The use of N-heterocyclic silylenes (NHSi) as ligands is a rapidly developing field. However, only a handful of f-element silylene complexes have been disclosed so far. Herein, we report the synthesis and characterization of a series of thermally stable d

A convenient metal-free photocatalytic hydrosilylation of a variety of linear and cyclic alkenes has been investigated. It was found that the free radical type photoinitiator Irgacure 2959 had a better effect on the hydrosilylation reaction; using 3 mol%

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.
