Ring-Walking Mediated by Ni–Ni Species as a Vehicle for Enabling Dis-tal C(sp2)–H Functionalization of Aryl Pivalates

Herein, we report the utilization of Ni-Ni species as a manifold for enabling a “ring-walking” event by a dynamic translocation of the metal center over the arene backbone. Experimental and computational studies support a translocation occurring via a 1,2-hydride shift. The synthetic applicability of the method is illustrated in a series of C–C bond for-mations that occur at distal C(sp2)–H sites of sim-ple aryl pivalates
