Induced electron transfer reaction of Cobalt (III) complexes of α�Hydroxy acids by 2, 2�-bipyridinium bromo chromate (BPBC) in the presence of surfactant medium

The kinetics mechanistic studied of BPBC with Cobalt (III) bound and unbound complexes of α-hydroxy acid in micellar medium at 323 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 electron transfer to Cobalt (III) centre. With increasing micelles concentration an increase in the rate is observed. Oxidation of Cobalt (III) complexes increases with increase in temperature. The kinetic and stoichiometric results have been accounted by a suitable mechanism.
