A sustainable Ni-catalyzed reductive acylation reaction of carboxylic acids via an electrochemical pathway is presented, affording a variety of ketones as major products. The reaction proceeds at ambient temperature using unactivated alkyl halides and N-hydroxyphthalimide (NHP) esters as coupling partners, which exhibits several synthetic advantages, including mild conditions and convenience of amplification
提出了一种通过电化学途径对羧酸进行可持续的镍催化还原酰化反应,提供多种酮作为主要产物。该反应在环境温度下使用未活化的卤代烷和N-羟基邻苯二甲酰亚胺 (NHP) 酯作为偶联配偶体进行,具有多种合成优势,包括条件温和且便于放大(6 mmol 规模反应的产率为 58%)。
