Aerobic Water-based Oxidation of 2,3,6-Trimethylphenol to Trimethyl-1,4-benzoquinone over Copper(II) Nitrate Catalyst

摘要

abstract_textpA catalytic method for aerobic water-based oxidation of 2,3,6-trimethylphenol to trimethyl-1,4-benzoquinone catalysed by copper(II) nitrate was achieved under mild conditions using dioxygen as an oxidant and water as a solvent. The catalyst shows high activity and selectivity in the direct oxidation of 2,3,6-trimethylphenol into trimethyl-1,4-benzoquinone. Since components used in the present system are cheap and available, our method offers a safe system in the synthesis of trimethyl-1,4-benzoquinone under halogen ions-free conditions./p/abstract_text
