The reaction of 1,3-dithiolane derivatives of ketones having α-hydrogen with lithium diisopropylamide results in fragmentation to the corresponding thioketone followed by further conversion in a few steps to the other intermediate species which, on trapping with alkyl halide, leads to a vinylic sulfide and/or a sulfide bearing a secondary alkyl group.
具有 α-氢的酮的 1,3-二硫杂环戊烷衍生物与二异丙基氨基锂的反应导致裂解为相应的硫酮,然后在几个步骤中进一步转化为其他中间体物种,在用烷基卤化物捕获时,产生乙烯基硫化物和/或带有仲烷基的硫化物。
