Abstract
Diphenylphosphinic chloride reacts with the superoxide anion radical in acetonitrile under mild conditions to form a peroxyphosphorus radical intermediate which shows strong oxidizing abilities for the epoxidation of olefins, oxidation of sulfides to sulfoxides, desulfurization of thioamides to amides, and oxidation of triarylphosphines to phosphine oxides. The radical can be trapped using a spin trapping method.
