A stereoselective method for the hydrosilylation of internal and terminal alkynes under 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 observed during this study, and the selectivity between the α- and β(E)-hydrosilylated products appears to be influenced to a certain degree by the nature of the hydrosilanes. The catalyst was recyclable up to five runs under gram scale conditions without any loss of the catalytic activity.

讨论了在二氯（乙二胺）铂（II）多相催化下内部和末端炔烃氢化硅烷化的立体选择方法。这种可商购的铂络合物在90°C的纯条件下运行，仅生成具有对称内部炔烃的（反式）Z-异构体，而末端炔烃则生成α-和β（E）-氢化硅烷化产物的混合物。在该研究中未观察到β（Z）-氢化硅烷化产物，并且α-和β（E）-氢化硅烷化产物之间的选择性似乎在一定程度上受氢硅烷性质的影响。该催化剂在克规模的条件下最多可循环使用五次，而催化活性没有任何损失。
