Phosphonium ylide catalysis through an oxidative quenching cycle has been developed for visible-light-driven C–H imidation of arenes and heteroarenes. The present protocol could be applied not only to trihalomethylative lactonization reactions involving trifluoromethyl, trichloromethyl, and tribromomethyl radicals but also to the first example of an organophotoredox-catalyzed imidative lactonization
通过氧化猝灭循环的鏻叶立德催化已被开发用于可见光驱动的芳烃和杂芳烃的 C-H 酰亚胺化。本协议不仅适用于涉及三氟甲基、三氯甲基和三溴甲基自由基的三卤甲基内酯化反应,而且适用于涉及以氮为中心的亲电子自由基物种的有机光氧化还原催化的亚胺化内酯化反应的第一个例子。
