The utility of a bipyridine periodic mesoporous organosilica, BPy-PMO, as a support material of a hydrosilylation catalyst was investigated in the hydrosilylation of phenylacetylene with trimethoxysilane. [PtMe2(BPy-PMO)] (1) exhibited a modera

The heterogeneous hydrosilylation of alkynes catalysed by platinum on titania is reported. A variety of hydrosilanes react with both terminal and internal alkynes to furnish the corresponding vinyl silanes in high yields and short reaction times as well as in a regio- and stereoselective manner. The catalyst can be easily recovered and reused in several consecutive cycles.

The reaction of(Rh(CO)2Cl)2 with di- and monoazadienes gives planar, four-coordinated rhodium(I) complexes Rh(CO)Cl(DAD) (III) and Rh(CO)Cl(MAD)2 (V), respectively, which catalyse the hydrosilylation of alkenes and alkynes.In a stereoselektive cis-addition symmetric internal alkynes give the corresponding silyl alkenes, while the catalytic addition of silane to terminal alkynes leads to the 2-silyl and cis-and trans-1-silyl-alkenes; their ratio depends on the controlling ligand and on the reaction conditions.With a stoichiometric amount of the silane the complexes III react under oxidative addition to give the rhodium(III) complexes Rh(H)(SiR3)(DAD)Cl (VI), which also catalyse the hydrosilylation.
