Reactions of ozonate and superoxide radical anions

Abstract

Potassium ozonate has been prepared by reaction of ozone with potassium superoxide dispersed in Freon-12. Orange solutions of potassium ozonate in benzene or toluene containing 18-crown-6 react with nitrone traps to give spin adducts mainly derived from the oxide radical anion, which is a decomposition product of the ozonate radical anion. With 2-methyl-2-nitrosopropane in toluene solution the ozonate gives five nitroxide radicals in whose formation the oxide radical anion is again implicated. With nitrosobenzene electron transfer occurs. Comparable reactions with superoxide are described.
