In the presence of electron acceptors such as CH2Cl2 or O2, the irradiation of AuCl2- or AuBr2- in acetonitrile led to the photooxidation of Au(I) to Au(III). AuCl4- and AuBr4- were formed as final products when additional halide was present. The reactive excited states were of the metal-centered ds type. The photooxidations were reversed in solutions of ethanol. AuCl4- and AuBr4- underwent a photoreduction to AuCl2- and AuBr2-, respectively.
