Oxidation of substituted toluenes by molecular oxygen at one atmosphere to the corresponding substituted benzoic acids in non-acidic solvents was investigated. Satisfactory oxidation of halo-, methoxy-, and cyano-toluenes were achieved using Co(C18H35O2)2/NH4Br or Co(OAc)2/NaBr/AcOH as catalysts in the presence of a radical initiator.
