2,3-Dihydro-2,3-dihydroxybenzoquinone dimer
Abstract
The product obtained by oxidation of benzoquinone with sodium chlorate in the presence of osmium tetroxide is a tricyclic dimer of 2,3-dihydro-2,3-dihydroxybenzoquinone. It reacts with acetic anhydride–sulphuric acid to give 1,2,6,7-tetra-acetoxydibenzo-p-dioxin.
