The oxidation of pentaamminecobalt(III) complexes of a-hydroxy acids and by Manganese(III) Perchlorate (Mn(III)(ClO4)3) in micellar medium yielding nearly 100% of carbonyl compounds and 100% Co(II) are ultimate products. In this reaction the rate of oxidation shows first order kinetics each in [Co(III)] and [Mn(III)(ClO4)3]. The unbound a-hydroxy acids yield about 100% of carbonyl compounds in presence of micelles. The rate of oxidation of Co(III) complexes of both bound and unbound a- hydroxy acids are enhanced more in the presence of cationic micelle Cetyltrimethylammonium bromide (CTAB), when compared to the anionic micelle of Sodium laurylsulphate (NaLS). The 1 mole of cobalt(III) complexes of a-hydroxy acids reacts with nearly 0.5 mole of Manganese(III) Perchlorate, similarly 1 mole of a-hydroxy acids reacts with nearly 1 mole of Manganese(III) Perchlorate. The reaction goes by free radical mechanism was proved by acrylonitrile polymerization. The appropriate methodology has been inducted.
