In the reactions of molecular oxygen with cobalt(II) amines, formation of μ-superoxo complexes has been identified on photolysis of cobalt(III) amine complexes [Co(trien)(NO2)2]ClO4 (1) and [Co(tetraen)(NO2)](ClO4)2 (2) in oxygen-saturated aqueous solution. The kinetics of oxygenation reactions has been followed by flash photolyzing the complexes 1 and 2 in aqueous and nonaqueous solvents and the rate constants for the formation of mononuclear superoxo complex and the μ-superoxo dinuclear complex has been determined at 25 ± 1°C. Photochemical routes for the preparation of μ-superoxo cobalt(III) complexes are suggested from this study.
