A Visible Light‐Mediated Regioselective Halogenation of Anilides and Quinolines by Using a Heterogeneous Cu‐MnO Catalyst

Abstract

A simple and practical heterogeneous Cu‐MnO catalyzed regioselective halogenation of anilides and quinolines under irradiation with household 40 W incandescent lamp was developed. This method uses a recyclable Cu‐MnO catalyst, 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.
