Electrochemical Gold Redox Catalysis

Abstract The high oxidation potential of Au(I)/Au(III) redox couple renders the development of gold‐catalyzed cross‐coupling reactions highly challenging. In the pursuit of Au(I)/Au(III) redox catalysis, various strategies, such as the use of stoichiometric oxidants, merged gold/photoredox systems, or ligand‐enabled approaches, have been adopted to achieve the oxidation of Au(I) to Au(III) complexes. Recently, electrochemical anodic oxidation‐based gold redox catalysis has emerged as a new technique to facilitate gold‐catalyzed cross‐coupling reactions. This concept article provides a succinct overview of electrochemical gold redox catalysis, highlighting the challenges and potential future developments.
