A copper‐based catalytic technique for the regioselective ortho CH cyanation of vinylarenes has been developed. This method provides an effective means for the selective functionalization of vinylarene derivatives. A copper‐catalyzed cyanative dearomatization mechanism is proposed to account for the regiochemical course of this reaction.
