The complex Cu-I(COD)(hfac) with COD = 1,5-cyclooctadiene and hfac = hexafluoroacetyl-acetonate shows two long-wavelength absorptions at lambda(max) = 308 and 241 nm which are assigned to hfac intraligand (IL) and Cu-I -->COD metal-to-ligand charge transfer (MLCT) transitions, respectively. The photolysis of Cu-I(COD)(hfac) in hexane leads to the release of the olefin and the subsequent disproportionation of Cu-I(hfac) to elemental copper and Cu-II(hfac)(2) with the quantum yields phi = 10(-3) at lambda(irr) = 313 nm and phi = 3 x 10(-3) at lambda(irr) = 254 nm. It is suggested that the reactive excited state is of the MLCT type.
