Oxidative Addition to Gold(I) by Photoredox Catalysis: Straightforward Access to Diverse (C,N)-Cyclometalated Gold(III) Complexes.

摘要: Herein, we report the oxidative addition of aryldiazonium salts to ligand-supported gold(I) complexes under visible light photoredox conditions. This method provides experimental evidence for involvement such a process in dual gold/photoredox-catalyzed reactions and delivers well-defined (C,N)-cyclometalated gold(III) species. The remarkably mild reaction conditions ability widely vary ancillary ligand make this potentially powerful synthetic tool access diverse systematic studies into their properties reactivity. Initial show that these species can undergo chloride abstraction afford Lewis acidic dicationic
