Abstract: (µ-peroxo)(µ-hydroxo)bis[bis(bipyridyl)-cobalt(III)] complex was synthesized by solution route. The prepared µ-peroxo complex was characterized by FT-IR and Electronic spectroscopy. The kinetics of biomimic oxidation of L-Valine by µ-peroxo complex in aqueous medium was studied potentiometrically. The reaction shows a first order dependence of rate with respect to each in the µ-peroxo complex concentration and hydrogen ion concentration. Variation of ionic strength has no significant effect on the rate. The reaction did not induce the polymerization by the addition of acrylonitrile. The activation and thermodynamic parameters have been calculated from the effect of temperature on the reaction rate. The main product was identified as the α-keto acid by spot test. A mechanism consistent with the observed kinetic results was proposed and discussed.
