ABSTRACT:

Nicotinium dichromate (NDC) oxidation of pentaamminecobalt (III) complexes of μ - hydroxy acids in micellar medium yielding nearly 100% of keto acid complex is ultimate product. The decrease in UV-Visible absorbance at 502 nm for Co(III) complex corresponds to nearly 0% reduction of the initial absorbance. The stoichiometry of unbound ligand and cobalt(III) complex is accounting for no reduction at the cobalt(III) centre. The kinetic and stoichiometric results have been accounted by a suitable mechanism.
