per-lithium (1) reacts with hex-1-yne, propyne, acetylene itself, phenylacetylene, and hex-3-yne to give the products of syn addition of the dimethylphenylsilyl group and the copper. The resultant vinylcopper reagents react with a variety of electrophiles, such as the proton, iodine, acyl and alkyl halides, enones, and epoxides, to give vinylsilanes. With the terminal alkynes, the silyl group becomes
双(二甲基苯基甲硅烷基)铜-锂(1)与己-1-炔,丙炔,乙炔本身,苯乙炔和己-3-炔反应生成二甲基苯基甲硅烷基和铜的顺式加成产物。所得的乙烯基铜试剂与各种亲电试剂反应,例如质子,碘,酰基和烷基卤化物,烯酮和环氧化物,得到乙烯基硅烷。在末端炔基的情况下,甲硅烷基以高水平的区域选择性与末端碳原子连接,结果最终产物为2,2-二取代的乙烯基硅烷。
