A Negishi cross-coupling of alkylpyridinium salts and alkylzinc halides has been developed. This is the first example of alkyl-alkyl bond formation via cross-coupling of an alkyl amine derivative with an unactivated alkyl group, and allows both primary and secondary alkylpyridinium salts to react with primary alkylzinc halides with high functional group tolerance. When combined with formation of the
烷基吡啶鎓盐和烷基卤化锌的根岸交叉偶联已被开发出来。这是通过烷基胺衍生物与未活化的烷基交叉偶联形成烷基-烷基键的第一个例子,并且允许伯烷基吡啶鎓盐和仲烷基吡啶鎓盐与具有高官能团耐受性的伯烷基卤化锌反应。当与伯胺形成吡啶鎓盐相结合时,该方法能够将 NH2 基团非规范地转化为具有广泛官能团耐受性的各种烷基取代基。
