| 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.
