Redox-active photocatalytic N^C cyclometalated gold(III) catecholate complexes
The redox properties and photocatalytic activity of four N^C cyclometalated Au(III) catecholate complexes were investigated. They proved competent for the photocatalytic C–H arylation of furan with aryldiazonium salts under green LED irradiation. UV–vis studies supported the formation of electron donor–acceptor adducts between the Au(III) catecholate complexes and diazonium salts, enabling photoinduced electron transfer and aryl radical generation. Electrochemical, EPR, and DFT studies evidenced ligand-centered redox activity and the formation of Au(III) semiquinone species.
