Bis(triphenylphosphine)palladium(II) chloride-cuprous iodide or tetrakis(triphenylphosphine)palladium(0)-cuprous iodide catalyze the formation of phenylethynylpentamethyldisilanes from substituted bromo- or iodo-benzenes and ethynylpentamethyldisilane. Concurrent siliconsilicon bond cleavage is not observed. The synthesis of 4-cyanophenylethynylheptamethyltrisilane from 4-bromobenzonitrile and et
氯化双(三苯基膦)钯(II)-碘化亚铜或四(三苯基膦)钯(0)-碘化亚铜催化由取代的溴-或碘-苯和乙炔基五甲基二硅烷形成苯基乙炔基五甲基二硅烷。没有观察到同时发生的硅硅键断裂。还证明了由4-溴苄腈和乙炔基庚甲基三硅烷合成4-氰基苯基乙炔基庚甲基三硅烷。
