摘要： The stable radical cation salts of phenothiazine and N-alkyl-phenothiazine(alkyl =methyl, ethyl, isohutyl, isopentyl and benzyl) hexachloroantimonate,per-chlorate, and iodide were prepared by means of one-electron oxidation with 2,2, 6,6-tetramethyl- 4-acetoxypiperidine oxoammonium hexachloroantimonate, perchloricacid, hydrogen peroxide, and molecular iodine, respectively.The radical cationswere characterized using ESRspectroscopy.Conformational analysis based on theESRparameters suggests that the radical cations adopt a planar configuration withthe nitrogen radical as the center.
