H. Kunkely et A. Vogler, PHOTOOXIDATION OF DICYANOAURATE(I) INDUCED BY METAL-TO-LIGAND CHARGE-TRANSFER EXCITATION, Zeitschrift fur Naturforschung. B, A journal of chemical sciences, 53(8), 1998, pp. 853-855
The irradiation of [Au(CN)(2)](-) in oxygen-saturated acetonitrile lea
ds to photooxidation of Au(I). In the presence of additional chloride
[Au(CN)(2)Cl-2](-) is formed with phi = 0.5 x 10(-4) at lambda(irr) =
254 nm. It is assumed that [Au(CN)(2)](-) in its metal-to-ligand charg
e transfer state undergoes an excited state electron transfer to oxyge
n in the primary photochemical step.
