A novel synthesis of trimethyl-p-benzoquinone: copper(II)–hydroxylamine catalysed oxygenation of 2,3,6-trimethylphenol with dioxygen
Abstract
2,3,6-Trimethylphenol was efficiently oxygenated to trimethyl-p-benzoquinone with molecular oxygen in the presence of a catalytic amount of copper(II) chloride–hydroxylamine in an alcoholic solvent at ambient temperature.
