Manganaelectro-catalyzed azidation of otherwise inert C(sp3)–H bonds was accomplished using most user-friendly sodium azide as the nitrogen-source. The operationally simple, resource-economic C–H azidation strategy was characterized by mild reaction conditions, no directing group, traceless electrons as the sole redox-reagent, Earth-abundant manganese as the catalyst, high functional-group compatibility
使用大多数用户友好的叠氮化钠作为氮源,完成了锰电催化的惰性 C(sp 3 )–H 键的叠氮化。操作简单、资源经济的C-H叠氮化策略具有反应条件温和、无导向基团、无痕电子作为唯一氧化还原试剂、地球丰富的锰作为催化剂、高官能团相容性和高化学选择性等特点。生物活性化合物的后期叠氮化阶段。通过实验、分光光度法和循环伏安法进行的详细机理研究为金属催化脂肪族自由基的形成以及随后在锰( III / IV )流形内的叠氮基自由基转移提供了强有力的支持。
