chloroethylenes are described. Symmetrical bis(trialkylsilyl)acetylenes are obtained in good yield from tetrachloroethylene, lithium and trialkylhalosilanes at −80° in tetrahydrofuran. When lithium and tetrachloroethylene are similarly allowed to react at −80° and then quenched with organosilicon halides, (chloroethynyl)triorganosilanes, R3SiCCCl, are produced. These can be coupled with lithium and chlorosilanes
描述了由氯乙烯制备有机甲硅烷基乙炔的一般方法。对称的双(三烷基甲硅烷基)乙炔可以在-80°C下于四氢呋喃中从四氯乙烯,锂和三烷基卤代硅烷获得高收率。当锂和四氯乙烯被类似地在-80至反应°,然后与有机硅卤化物,(氯乙炔基)三有机硅烷,R猝灭3 SiCCCl,生产。这些可以与锂和氯硅烷偶联以得到不对称取代的双(有机甲硅烷基)乙炔。三氯乙烯,锂和三烷基氯硅烷可得到适当的乙炔基三烷基硅烷R 3 SiC fairCH。对称的双(有机甲硅烷基)乙炔也可以由顺式或反式制备-1,2-二氯乙烯,烷基锂化合物和氯硅烷。
