Oxidation of Pentaamminecobalt (III) complexes of α-hydroxy acids by Mn (III) perchlorate, Mn (III) acetate and Mn(IV) heteropolyanion in micellar medium
yielding nearly 100% of carbonyl compounds are ultimate products. This oxidation as a diagnostic tool to find out the fraction proceeding by synchronous cleavages of O-H and C-C bonds. It has been found that the rate of oxidation of Co(III) complexes of both bound and unbound α- hydroxy acids are enhanced more in the presence of cationic micelle of Cetyltrimethylammonium bromide (CTAB), when compared to the anionic micelle of Sodium laurylsulphate (NaLS) The 1 mole of cobalt(III) complexes of αhydroxy acids reacts with nearly 0.5 mole of Mn(III) perchlorate, Mn(III) acetate and Mn(IV) heteropolyanion, similarly 1 mole of α-hydroxy acids reacts with nearly 1 mole of Mn(III) perchlorate, Mn(III) acetate and Mn(IV) heteropolyanion respectively. The reaction goes by free radical mechanism was proved by acrylonitrile polymerization. The appropriate methodology has been inducted.
