Stable nitroxide radicals 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 nitroxide radicals are discussed and a number of cases of magnetic non-equivalence
通过氧化1-羟基二氢吲哚获得稳定的氮氧自由基,该1-羟基二氢吲哚通过使有机金属化合物作用于2-苯基饱和脂肪烃和芳基衍生物而制得。在这两种情况下,与类似的已知化合物相一致,均获得了N约为9高斯的氮氧化物。讨论了许多氮氧自由基的ESR光谱,并揭示了许多与不对称碳相邻的亚甲基质子在磁性上不等价的情况。
