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.
