ortho-selective C–H halogenation methodology is reported herein. The highlight of the work is the highly selective C(sp2)–H functionalization of benzyl nitriles in the presence of activated C(sp3)–H bond, which results in good yields of the halogenated products with excellent regioselectivity. Along with benzyl nitriles, aryl Weinrebamides and anilides have been evaluated for the transformation using aprotic

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
