Stablenitroxideradicals were obtained by the oxidation of 1-hydroxyindolines prepared by allowing the organo-metallic compounds to act upon 2-phenylisatogen and arylimino-derivatives. In both cases nitroxides are obtained with a N of approximately 9 gauss, in agreement with similar known compounds. The ESR spectra of numerous nitroxideradicals are discussed and a number of cases of magnetic non-equivalence
