Electron spin resonance studies of oxidation. Part VII. Iminoxy radicals. Part II. Radicals from benzaldoximes and related oximes

Abstract

The electron spin resonance spectra of the iminoxy radicals derived by the one-electron oxidation of benzaldoximes and related oximes have been measured in solution. The results provide information about the conformational preferences of these radicals and about the dependence of the hyperfine splitting on their geometry. Attention is drawn to the relatively large splittings due to fluorine and chlorine in these σ-radicals, as compared with π-radicals.
