Synthesis of new vinylsilanes containing an asymmetric silicon via platinum catalyzed hydrosilylation of acetylene and monosubstituted alkynes

Gevorgyan, Vladimir,Borisova, Larisa,Popelis, Juris,Lukevics, Edmunds,Foltynowicz, Zenon,et al.

, p. 15 - 22 (2007/10/02)

A series of new racemic vinylsilanes has been obtained by hydrosilylation reaction of acetylene and monosubstituted alkynes with (+/-)α-NpPhMeSiH and (+/-)-N(CH2CH2O)3SiCH2PhMeSiH in the presence of platinum-containing catalysts.
