A copper‐catalyzed CC bond cleavage reaction of 1,3‐dicarbonyl compounds with 2‐iodoanilines was developed. In this process, the ortho effect played an important role in the reactivity and a new reaction pathway that involved a (2‐aminophenyl)‐bis‐(1,3‐dicarbonyl) copper species was clearly observed by a time‐course HRMS analysis of the reaction mixture. Unlike the previous reports, both the nucleophilic
铜-催化Ç 与2- iodoanilines 1,3-二羰基化合物C键裂解反应被开发。在此过程中,邻位效应在反应性中起着重要作用,并且通过时程HRMS分析可以清楚地观察到涉及(2-氨基苯基)-双-(1,3-二羰基)铜物种的新反应途径。反应混合物。与以前的报道不同,1,3-二羰基化合物的亲核和亲电子部分都通过CC键裂解与2-碘苯胺偶联形成邻-(N-酰基氨基)芳基酮,可以有效地转化为多取代基吲哚。
