Vanadyl(IV)-acetylacetonate-catalyzed oxidation of cyclohexane with H(2)O(2), at 40 degrees C under air atmosphere, has been studied in the presence of small quantities of oxalic acid. The process efficiency is increased by this additive and depends on the nature of the solvent (MeCN >= MeOH > Me(2)CO >= 2-PrOH > EtOH). The relationships between the results (conversion, yield) and the electrochemical characteristics of the reaction solution (relative permittivity, redox-potential) are highlighted and discussed.
