a mixture of (E)-1,2-bis(trimethylsilyl)ethene and (E)-1-triethylsilyl-2-trimethylsilylethene. The yield of (E-1,2-bis(trimethylsilyl)ethene increases with an increase in the molar ratio of trimethylsilylethene to triethylsilane. The Ru3(CO)12-catalyzed reaction of trimethylsilylethene in the presence of a catalytic amount of triphenylsilane also gives (E)-1,2-bis(trimethylsilyl)ethene in good yields
三甲基甲硅烷基乙烯与三乙基硅烷的Ru 3(CO)12催化反应得到(E)-1,2-双(三甲基甲硅烷基)乙烯和(E)-1-三乙基甲硅烷基-2-三甲基甲硅烷基乙烯的混合物。(E -1,2-双(三甲基硅烷基)乙烯的产率随三甲基硅烷基乙烯与三乙基硅烷的摩尔比的增加而增加。在催化量的三苯基硅烷存在下,Ru 3(CO)12催化三甲基硅烷基乙烯的反应产生良好收率的(E)-1,2-双(三甲基甲硅烷基)乙烯。三有机甲硅烷基如二甲基(乙氧基)甲硅烷基乙烯和三乙氧基甲硅烷基乙烯也产生相应的(E)-1,2-二烯丙基。苯乙烯与三甲基甲硅烷基乙烯的相似催化反应以良好的收率得到1-三甲基甲硅烷基-2-苯基乙烯。
