regioselective halogenation of anilides and quinolines with heterogeneous Cu‐MnO catalyst and under irradiation with a household 40 W incandescent lamp was developed. The catalyst is recyclable, acetonitrile as an industrially friendly solvent, and economic N‐halo succinimides as a halogenating source. The reaction is scalable and well tolerated with a broad range of functional groups.
开发了一种简单实用的方法,用于使用多相Cu-MnO催化剂并在家用40 W白炽灯的照射下,对苯胺和喹啉进行区域选择性卤化。该催化剂是可回收的,乙腈为工业上友好的溶剂,经济的N卤代琥珀酰亚胺为卤化源。该反应是可扩展的并且具有广泛范围的官能团的良好耐受性。
