A simple method for direct C–H imidation is reported using a new perester-based self-immolating reagent and a base-metal catalyst. The succinimide products obtained can be easily deprotected in situ (if desired) to reveal the corresponding anilines directly. The scope of the reaction is broad, the conditions are extremely mild, and the reaction is tolerant of oxidizable and acid-labile functionality
报道了一种使用新的过酯基自焚试剂和贱金属催化剂直接 C-H 酰亚胺化的简单方法。获得的琥珀酰亚胺产物可以很容易地原位脱保护(如果需要)以直接显示相应的苯胺。该反应范围广,条件极其温和,反应耐受可氧化和酸不稳定的官能团、多个杂原子和芳基碘。机理研究表明,二茂铁 (Cp2Fe) 在过酯试剂的分解中扮演电子穿梭机的角色,提供准备添加到芳香系统中的琥珀酰亚胺自由基。
