✦ Synopsis
a-Ketonitroxides (nitroxones) are relatively persistent nitroxides produced either from oxidation of hydroxamic acids (1) or by spin trapping (2). Since nitroxones are isoelectronic with semidiones (3) it is reasonable to assume that the carbonyl and nitroxyl functions are part of a planar 5n-electron system (4,5). This assumption implies that the unpaired electron is delocalized over all four atoms of the x-system (4). Thus finite spin density
