regioselective method for para-amination of activated arenes has been developed through a combination of iron and copper catalysis. A diverse range of products were obtained from an operationally simple one-pot, two-step procedure involving bromination of the aryl substrate with the powerful Lewis acid iron(III) triflimide, followed by a copper(I)-catalysed N-arylation reaction. This two-step dehydrogenative
通过铁和铜催化的结合,已经开发出一种温和,有效和区域选择性的方法来活化芳烃的对氨基化。从操作简单的一锅,两步程序(包括用强力的路易斯酸三氟化铁路易斯酸溴化芳基),然后进行铜(I)催化的N-芳基化反应,即可获得各种各样的产品。用于芳族CH键与非活化胺的区域选择性偶联的两步脱氢方法适用于苯甲醚,苯酚,苯胺和乙苯胺型芳基化合物。重要的是,将芳烃底物用作限制性试剂,并且在转化过程中不需要保护基团的操作。
