A mild, efficient electrochemical approach to the site-selective direct C-H amidation of benzene and its derivatives with acetonitrile and benzonitrile has been developed. It has been shown that joint electrochemical oxidation of various arenes in the presence of a copper salt as a catalyst and nitriles leads to the formation of N-phenylacetamide from benzene and N-benzylacetamides from benzyl derivatives
已经开发了一种温和、有效的电化学方法,用于苯及其衍生物与乙腈和苄腈的位点选择性直接 CH 酰胺化。已经表明,在铜盐作为催化剂和腈的存在下,各种芳烃的联合电化学氧化会导致苯形成 N-苯基乙酰胺和苄基衍生物形成 N-苄基乙酰胺(产率高达 78%)。该工艺的一个有利特点是符合绿色化学标准的温和条件(室温、环境压力、无强氧化剂)。
