Styrylsilanes serve as new couplingreagents for introducing organic functional groups on silica and glass surfaces. Functionalized styrylsilanes, which are readily prepared via catalytic hydrosilylation of the corresponding phenylacetylenes with silanes, are immobilized on silica through acid catalyzed processes under mild conditions.
Dichloro(ethylenediamine)platinum(II), a water-soluble analog of the antitumor cisplatin, as a heterogeneous catalyst for a stereoselective hydrosilylation of alkynes under neat conditions
hydrosilylation of internal and terminal alkynesunder heterogeneous catalysis by dichloro(ethylenediamine)platinum(II) is discussed. This commercially available platinum complex operates under neat conditions at 90 °C, producing exclusively the (trans) Z-isomer with symmetrical internal alkynes, while terminal alkynes produce a mixture of α- and β(E)-hydrosilylated products. No β(Z)-hydrosilylated product was
