direct convergent synthesis to target molecules from easily-available and cheap substrates has been developed. A wide range of alkyl aryl ketones are accessed from alkylhalides, aryl iodides and propyl chloroformate under mild conditions, avoiding the use of over-stoichiometric reductants, excess quantities of additives and activators, and superstoichiometric CO gas or metal carbonyl complexes which are
电还原交叉亲电子偶联作为构建具有挑战性的 C-C 键的一种强大、绿色和高效的方法,越来越受到有机化学家的关注。以前的大部分工作都集中在直接的双亲电试剂交叉偶联上。在这项工作中,开发了镍催化的三亲电试剂电还原交叉亲电试剂偶联,它可以从易于获得且廉价的底物中直接聚合合成目标分子。在温和条件下,从烷基卤化物、芳基碘化物和氯甲酸丙酯中获得多种烷基芳基酮,避免使用超化学计量的还原剂、过量的添加剂和活化剂,以及超化学计量的 CO 气体或有毒的金属羰基络合物,对环境不友好,处理起来不方便。放大实验表明,与传统合成相比,电合成具有良好的可扩展性。通过增加电流可以实现高化学选择性。机理研究表明,从阴极到 Ni 催化剂的电子转移速率在该协议中起着至关重要的作用。我们的方法在交叉亲电子偶联中展示了一种新型的电化学选择性控制策略。
