ABSTRACT
The kinetics of oxidation of [N-isopropylidene - hydrazine-s-methyldithio-carboxylate] cobalt [II] complex by N-bromosuccinimide [NBS] and N-bromophthalimide [NBP] in benzene solvent were studied spectrophotometrically at lambda = 300 - 310 nm and at 281-297 K for a range of complex and oxidant concentrations. The reaction exhibited a first order dependence on both reactants. The detection of the initial cobalt [III] products which are slowly converted to the final cobalt [III] supports an inner-sphere mechanism for the oxidation of the complex by both oxidants. Under identical experimental conditions, the extent of oxidation using the oxidizing agents is in the order NBS > NBP. GC-MS analysis for the reaction mixture after completion of the oxidation reaction indicates the presence of both succinimide and phthalimide as side products of the oxidation process
