摘要

Abstract: Treatment of 4-unsubstituted and 4-halogenated phenols with PbO2 and 70% HClO4 in AcOH afforded the corresponding p-benzoquinones in fair to high yields. The oxidation of 4-substituted 2, 6-di-tert-butylphenols 6 with PbO2 and 70% HClO4 in acetone gave 2, 6-di-tert-butyl-p-benzoquinone (2). Key words: p-benzoquinones, phenols, lead dioxide, 70% HClO4
