A 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.
