Kinetics of the photoreduction of bis(2,4-pentanedionato)copper(II) in chloroform
Under 254 nm irradiation in chloroform, bis(2,4-pentanedionato)copper(II) is converted to CuCl·2HCl, from which CuCl precipitates at concentrations of 10−3 M or higher. The photoreaction appears to be completely solvent-initiated, that is, the rate depends on the fraction of light absorbed by the solvent. Both radical dotCCl3 radicals and HCl, produced photolytically, are able to initiate the reaction.
