  • Descrição: Iridium‐catalyzed electrochemical C−H activation was accomplished within a cooperative catalysis manifold, setting the stage for electrooxidative C−H alkenylations through weak O‐coordination. The iridium‐electrocatalyzed C−H activation featured high functional‐group tolerance through assistance of a metal‐free redox mediator through indirect electrolysis. Detailed mechanistic insights provided strong support for an organometallic C−H cleavage and a synergistic iridium(III/I)/redox catalyst regime, enabling the use of sustainable electricity as the terminal oxidant with improved selectivity features. Cooperation: Electrooxidative twofold C−H alkenylation by weak O‐assistance was accomplished by synergistic indirect iridium‐catalyzed electrolysis, enabling unique levels of chemoselectivity.
