The reaction of triethylsilylpotassium with vinyltrimethylsilane (I) in benzene at room temperature gave as principal products 1-(trimethylsilyl)-2-(triethylgermyl)ethane, phenylpotassium, phenyltrimethylsilane and ethylene. The same reaction was found to occur between triethylgermylpotassium and I. The results suggest that the addition product, Me3SiCH(K)CH2MEt3 (M = Si or Ge), formed initially, behave
室温下,三乙基甲硅烷基钾与乙烯基三甲基硅烷(I)在苯中的反应得到1-(三甲基甲硅烷基)-2-(三乙基锗基)乙烷,苯基钾,苯基三甲基硅烷和乙烯作为主要产物。发现三乙基锗烷基钾与I之间发生相同的反应。结果表明,最初形成的加成产物Me 3 SiCH(K)CH 2 MEt 3(M = Si或Ge)充当可以反应的活性有机金属试剂。用苯得到Me 3 SiCH 2 CH 2 MEt 3和苯基钾。我的隔离3SiPh建议硅烷(I)也与PhK反应,导致乙烯基-硅裂解。如果进行三乙基锗锂反应,则不会发生金属化和CSi键断裂。
