Photochemical Generation of μ-Amido-μ-peroxo-bis Complex from the Corresponding μ-Hyperoxo Complex in Neutral Aqueous Solution

Article abstract of DOI:10.1246/bcsj.61.3338

A μ-amido-μ-hyperoxo complex, <(en)2Co(NH2,O2^-)Co(en)2>⁴⁺, was found to generate the corresponding μ-peroxo complex, together with mononuclear cobalt(III) complexes upon irradiation with near-ultraviolet light in a neutral aqueous solution.The result is different from that obtained in an acidic aqoueous solution, in which the products are ³⁺ and Co_aq²⁺.The photochemical reaction mechanisms are discussed.
