Abstract: Bridging superoxide in [(en)(dien)CoIII(O2)CoIII(en)(dien)]5+ quantitatively oxidizes N(III) to N(V), itself being reduced to hydroperoxo group. Kinetic study and solvent isotope effect indicate two parallel paths: (a) electron transfer and (b) proton coupled electron transfer. The present study also indicates that the ancillary ligands affect the reaction rate substantially. Studies on redox behavior of metal bound superoxide are not many and this study is expected to shed some light on the redox nature of metal bound superoxide.
