Abstract The catalyticoxidative domino degradation of phenols was investigated. Hydrogenperoxide (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

Hydrolysis of biorenewable muconic acids or their corresponding lactones in high temperature water allows the selective synthesis of levulinic acids. This enables direct access to novel substituted levulinic acidsfrom biomass, creating novel opportunities for industrial applications. 3-Propyllevulinic acid was used to synthesize a novel plasticizer which performed equally well as a commercial, petrochemical
