Abstract: The catalyst system Pt(DVDS)-proazaphosphatrane, containing a bulky aminophospine ligand, was used to catalyze the hydrosilylation of various terminal alkynes with Et3SiH or Ph3SiH. These reactions occurred efficiently and stereo- and regioselectively. Anti-markonikov E-products or Markonikov α-products were obtained with a selectivity >95% in a yield >90% except in one case where the selectivity and the yield were a little lower.

Key words: Terminal alkyne, Hydrosilylation, Vinylsilane, Pt catalyst system, Nonionic super base
