Nitroxyl radicals (N-oxyls or nitroxides), as exemplified by TEMPO (2,2,6,6-tetramethylpiperi-dinyl-l-oxy), AZADO (2-azaadamantane N-oxyl), and PINO (phthalimidiy N-oxyl), represent a stable class of organic radicals that exhibit unique properties and reactivity. The diverse and exotic chemistry of these compounds has been found versatile use in electron spin resonance (ESR) studies as spin labels, in biological studies as antioxidants, as charge carriers for energy storage, as mediators in polymerization reactions, and as catalysts in chemical and electrochemical oxidation reactions. This article describes recent synthetic applications of the two most prominent classes of N-oxyl compounds, namely, aminoxyl and imidoxyl species, to effect useful oxidative transformations.
