Electrochemical Oxidative Carbonylation/Coupling Reaction using Anode to Oxidize the Trasition‐Metal‐Catalyst and Substrate

Abstract We reported an electrochemical oxidative carbonylation of N ‐phenylpyridin‐2‐amine derivatives under mild condtions without an external oxidant. Our approach demonstrated a novel electrochemical oxidative carbonylation reaction mode in which the simultaneous reaction of catalyst and substrate with the anode has been developed. Furthermore, an electrochemical C−H activation for the synthesis of cyclized pyridinium ion has also been realized. Mechanistic investigations suggested that the process involved a “Pd II /Pd III /Pd I /Pd II ” catalytic cycle, and H 2 was generated at the cathode.
