The first highly efficient ligand-controlled regio- and stereodivergent intermolecular hydrosilylations of internal alkynes have been disclosed. Cationic ruthenium complexes [Cp*Ru(MeCN)3](+) and [CpRu(MeCN)3](+) have been demonstrated to catalyze intermolecular hydrosilylations of silyl alkynes to form a range of vinyldisilanes with excellent but opposite regio- and stereoselectivity, with the former

2-disubstituted alkenylsilanes. The obtained alkenylsilane was subjected to reaction with α,β-unsaturated carbonyl compounds in the presence of a rhodium catalyst to undergo conjugate addition. One-pot hydrosilylation-conjugate addition with a rhodium catalyst was also performed.

A mild, selective and facile synthesis of vinylsilanes via a recyclable platinum nanoparticle catalysed hydrosilylation of alkynes is reported. Various functionalizedalkynes are selectively hydrosilylated to furnish functional β-E vinylsilanes in high yields. The catalytic effectiveness, ease of catalyst recovery and recyclability of the polysiloxane stabilized Pt-nanoparticle catalyst are the major
