| Abstract: | The rates of photo reduction of pentaamminecobalt(III) complexes of ɑ-hydroxy acids at 254 nm are comparable to the rates of formation of cobalt(II) and the corresponding carbonyl product. This is suggestive of electron transfer to cobalt(III) and C-C bond cleavage in an almost concerted manner. The charge transfer to metal ion has an excited state as t facilitating photoreduction of cobalt/Ill). The d - π back bonding is ligand-centered, favouring C-C bond cleavage. In all these reactions, the quantum yield of Co2+ is nearly 0.24. |
