Oxidative C–H functionalization has faced considerable limitations by the need for stoichiometric amounts of chemical oxidants. In sharp contrast, we herein present the merger of electrosynthesis with non-toxic manganese catalysis for oxidative C–H arylations and C–H alkylations with electricity as the terminal oxidant. Mechanistic experimental studies as well as cyclic voltammetry and scanning electron microscopy analysis were suggestive of an initial fast C–H activation. Computational studies highlighted the unique features of manganaelectro-catalyzed C–H arylations for the use of monodentate benzamides, contrasting with ferraelectrocatalysis that remains limited to strongly coordinating N,N-bidentate directing groups.

弱配位酰胺辅助锰电催化的氮杂C-H芳基化和C-H烷基化

由于需要化学计量的化学氧化剂，氧化 C-H 功能化面临着相当大的限制。与此形成鲜明对比的是，我们在此展示了电合成与无毒锰催化的结合，用于氧化性 C-H 芳基化和以电为终端氧化剂的 C-H 烷基化。机械实验研究以及循环伏安法和扫描电子显微镜分析表明初始快速 C-H 活化。计算研究强调了锰电催化的 C-H 芳基化在使用单齿苯甲酰胺时的独特特征，而铁电催化仍然仅限于强配位的N，N-双齿导向基团。
