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.

Paragraph 0033; 0055; 0056, (2017/02/24)
PROBLEM TO BE SOLVED: To provide a production method which makes it possible to produce an organic silane compound efficiently and inexpensively by improving a catalyst for use in hydrosilylation reaction of alkene and alkyne. SOLUTION: This invention provides a method of producing an organic silane compound, including reaction between alkene and/or alkyne and hydrosilane in the presence of a catalyst, wherein an iron-containing nanoparticle with a solvent coordinated on the surface is used as a catalyst so that an organic silane compound can be produced efficiently and inexpensively.
