Abstract

Three reductones, 2, 3-dihydroxy-4, 4-diphenyl-2, 5-cyclohexadien-l-one (11), 3, 4- dihydroxycoumarin (35), and 3, 4-dihydroxyspiro [5.5] undecan-3-en-4-one (641, were prepared and subsequently reacted with superoxide anion radical (02'-), generated from KO2 and 18-crown-6 polyether. The reactions were carried out in aprotic media and quenched with methyl iodide which facilitates the trapping of the various oxyanions ...
