Reactivity of potassium superoxide in heterogeneous phase: Oxidation of naphthalenediols and hydroxylated naphthoquinones

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.

OXYDATION DU NAPHTALENEDIOL-1,5 PAR LE SUPEROXYDE DE POTASSIUM EN PHASE HETEROGENE

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.

Ebenaceae Extractives. Part 8. The Structure of Diosquinone and Reactions of Related Quinone Epoxides

Diosquinone, from Diospyros tricolor, is shown to be the naphthoquinonylnaphthoquinone epoxide (2).Juglone epoxides react with chloroform and with ethanol with the formation of chloro- and chlorohydroxy-juglones and of ethoxy- and ethoxyhydroxy-juglones respectively.
