A cobalt-catalyzed regioselective C–H halogenation methodology is reported herein. The highlight of this work is the highly selective C–H functionalization of anilides, which results in high-yielding, versatile, and practical halogenated products. Thereby, brominations, chlorinations and iodinations of many electron-rich and electron-deficient anilides were achieved in a highly selective fashion. Mechanistic studies with respect to the pathway of the reaction are also described.
