Oxidation of dihydroxynaphthalenes by potassium superoxide (KO2) in heterogeneous aprotic media yields mono- or dihydroxynaphthoquinones, depending on the relative position of the hydroxy groups on the naphthalene moiety. The reaction proceeds mainly at the solid-liquid interface and naphthoquinones can be obtained with good yields.

The oxydation of 1,5-dihydroxynaphthalene by potassium superoxide is essentially an interfacial solid/liquid reaction, which leads to 2,5- and 3,5-dihydroxy-1,4-naphthoquinones.The reaction proceeds in two steps through the formation of 5-hydroxy-1,4-naphthoquinone.The mechanism of the reaction is discussed.
