Abstract

The kinetics mechanistic studied of BPBC with Cobalt (III) bound and unbound complexes of α-amino acid in micellar medium at 300 K in 50% acetic acid – 50 % water. In this reaction the rate of oxidation shows pseudo first order kinetics each in Cobalt (III) and BPBC. It rules out the synchronous C-C bond fission and N-H bond fission. With increasing micelles concentration an increase in the rate is observed. Oxidation of Cobalt (III) complexes increases with increase in temperature. The added CTAB enhances the rate of oxidation of a reaction much more than NaLS. The kinetic and stoichiometric results have been accounted by a suitable mechanism.
