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
