The catalytic oxidative domino degradation of phenols was investigated. Hydrogen peroxide (30% aq.) was used as an oxidant and 2,2′-dinitro-4, 4′-ditrifluoromethyldiphenyl diselenide 4e as a catalyst. The products were muconic acid 5, and muconolactones muconolactones - 5-carboxymethylfuran- 2(5H)-ones 7 and 9. Phenols with alkyl groups at 2 or 4 positions of the benzene ring were converted regioselectively to corresponding muconolactones substituted at alkenylene ring carbon atoms. The reaction mechanism is proposed. Copyright Taylor & Francis Group, LLC.

Reaction of creosol (2-methoxy-4-methyl-phenol) with oxygen in alkaline aqueous solution gave several neutral and acidic compounds which were identified.By quantitative determination of the degradation products an evaluation of the degradation pathways was possible. - Keywords: Cyclohexadienons as intermediates; Oxygen bleaching; Oxygen pulping; Phenol oxidation; Gas chromatography of methyl esters
