catalyst-free and exogenous-oxidant-free conditions, a series of C-3 aminated imidazo[1,2-a]pyridines were synthesized by electrochemical intermolecular oxidative C–H/N–H cross-coupling. Furthermore, by using a catalytic amount of ferrocene as the mediator, electrochemical intramolecular oxidative C–H/N–H cross-coupling for the synthesis of 10H-benzo[4,5]imidazo[1,2-a]indole derivatives has also been accomplished
在无金属催化剂和无外源氧化剂的条件下,通过电化学分子间氧化C–H / N–H交叉偶联反应,合成了一系列C-3胺化的咪唑并[1,2- a ]吡啶。此外,通过使用催化量的二茂铁作为介体,用于合成10 H-苯并[4,5]咪唑并[1,2- a ]吲哚衍生物的电化学分子内氧化C–H / N–H交叉偶联具有也完成了。
