Electrochemical Gold‐Catalyzed 1,2‐Difunctionalization of C−C Multiple Bonds**

Abstract Herein, we disclose the first report of 1,2‐difunctionalization of C−C multiple bonds using electrochemical gold redox catalysis. By adopting the electrochemical strategy, the inherent π‐activation and cross‐coupling reactivity of gold catalysis are harnessed to develop the oxy‐alkynylation of allenoates under external‐oxidant‐free conditions. Detailed mechanistic investigations such as 31 P NMR, control experiments, mass studies, and cyclic voltammetric (CV) analysis have been performed to support the proposed reaction mechanism.
