C−H/C−C functionalizations with methylenecyclopropanes (MCPs) were accomplished with a versatile base‐metal catalyst. A robust manganese(I) complex enabled the expedient annulation of MCPs by synthetically meaningful ketimines to deliver, upon one‐pot hydroarylation, densely substituted polycylic anilines in a step‐economical fashion. Mechanistic studies provided strong support for a facile organometallic
使用亚甲基环丙烷(MCP)进行C / H / C-C官能化反应是通过通用的贱金属催化剂完成的。强大的锰(I)配合物通过合成意义上的酮亚胺使MCP的便捷脱环成为可能,从而在一步锅加氢芳基化反应中以分步经济的方式提供了稠密取代的多环苯胺。机理研究为简便的有机金属CH锰提供了有力的支持,而典型的钴,钌,铑和钯催化剂被发现完全无效。
