Kinetics of aerobic liquid-phase oxidation of organic compounds

The work discussed the role of cobalt and manganese complexes in the liquid-phase catalytic benzylic oxidation in polar and apolar media. Evidence that hydrocarbon is involved during oxidation with the transition metal ion is presented. It is supposed that reaction acceleration caused by bromide salts is due to the increase in the rate of the electron transfer and no initiation by bromine atoms exist. The reasons for different product selectivity in the presence of cobalt and manganese are explained and the synergistic effects of mixed catalysts are discussed. Thus cobalt is active in the oxidation of hydrocarbons and alcohols, while manganese is active in oxidation of carbonyl compounds. These assumptions allowed to build a system of differential rate equations.
