  苯二氨基甲基化中的潜在卡宾：机理和实际应用

  摘要：

  由于甲硅烷基团容易迁移，甲硅烷基甲脒1与其碳烯形式1'处于平衡状态。1与各种取代的氟苯的反应随着亲核卡宾1'的插入而进行在混合试剂后进入最酸性的 C-H 键，不需要任何催化剂。根据 DFT 计算，通过三元过渡态结构进行的插入反应的经典解释需要高活化能。相反，预计将芳香底物中酸性最强的质子转移到卡宾碳上的活化势垒较低。下一步，形成的离子对向产物的无障碍重排完成了该过程。取代苯在与甲硅烷基甲脒反应中的反应性可以通过计算的C-H 氢的p K a (DMSO) 值粗略评估。具有 p K a的苯衍生物约 少于 31 个可以进行 C-H 插入。该反应提供缩醛胺作为第一批产物，它可以很容易地通过酸水解转化为相应的醛。由于甲硅烷基甲脒1对许多官能团具有耐受性，该反应可应用于多种苯衍生物，使其成为有机合成应用的可靠策略。
