A highly efficient Cu-catalyzed 1,4-difunctionalization of isoquinolinium salts was developed with ether and X– (X = Br, Cl) as the halogen source under mild conditions. This transformation involves the combination of oxidative coupling and copper-catalyzed halogen atom-transfer radical processes. This method not only provides an efficient way to prepare various substituted azaarenes but also achieves
在温和条件下,以醚和X –(X = Br,Cl)作为卤素源,开发了一种高效的Cu催化的异喹啉鎓盐的1,4-双官能团。该转变涉及氧化偶联和铜催化的卤素原子转移自由基过程的组合。该方法不仅提供了一种制备各种取代的氮杂芳烃的有效方法,而且还通过自由基过程实现了从卤素阴离子和亲核碳原子选择性构建C(sp 2)–X(X = Br,Cl)键。
