Regioselective Oxidation of Phenols to <i>o</i>-Quinones with <i>o</i>-Iodoxybenzoic Acid (IBX)

Abstract

[reaction: see text] An efficient regioselective method for oxidation of phenols to o-quinones is reported. When this procedure is combined with a subsequent reduction, it proves to be useful for the construction of a variety of catechols.
