Herein, an electrochemical hydrogen atom transfer (HAT) strategy for C(sp2)–H formylation of electron-deficient quinolines and isoquinolines is described. The cheap methanol acts as a formyl source with a catalytic amount of N-hydroxyphthalimide (NHPI) as the hydrogen atom transfer (HAT) catalyst. The advantages of this reaction are transition-metal-catalyst- and chemical-oxidant-free conditions, and
本文描述了缺电子喹啉和异喹啉的C(sp 2 )–H 甲酰化的电化学氢原子转移 (HAT) 策略。廉价的甲醇作为甲酰源,催化量的N-羟基邻苯二甲酰亚胺 (NHPI) 作为氢原子转移 (HAT) 催化剂。该反应的优点是无过渡金属催化剂和化学氧化剂的条件,并且该方案也可以应用于喹啉的直接C(sp 2 )–H乙酰化或丙酰化。
