  Ferromagnetic Behavior of Formyl-Group-Carrying Stable Thioaminyl Radicals¹

  摘要：

  Four formyl-group-carrying thioaminyl radicals were generated, and one radical could be isolated as radical crystals. Magnetic susceptibility measurements of the isolated radical showed a ferromagnetic regular linear-chain interaction of 2J/k(B) = 3.2 K, which was explained in terms of the X-ray crystallographic results.

  Stable Thioaminyl Radicals Having Functional Groups:  Generation, ESR Spectra, Isolation, X-ray Crystallographic Analyses, and Magnetic Characterization of N-(Arylthio)-4-(ethoxycarbonyl)-2,6-diarylphenylaminyls, N-(Arylthio)-4-acetyl-2,6-diarylphenylaminyls, and N-(Arylthio)-4-cyano-2,6-diarylphenylaminyls¹

  摘要：

  Oxidation of N-(arylthio)-4-(ethoxycarbonyl)-2,6-diarylanilines (9), N-(arylthio)-4-acetyl-2,6-diarylanilines (10), and N-(arylthio)-4-cyano-2,6-diarylanilines (11) with PbO2 yielded quite persistent N-(arylthio)-4-(ethoxycarbonyl)-2,6-diarylphenylaminyls (4), N-(arylthio)-4-acetyl-2,6-diarylphenylaminyls (5), and N-(arylthio)-4-cyano-2,6-diarylphenylaminyls (6), respectively, and they were isolated as pure radical crystals. On the other hand, N-(arylthio)-4-nitro-2,6-diarylphenylaminyls (6), and N-(arylthio)-4-chloro-2,6-diarylphenylaminyls (7), were unstable and soon decomposed. The X-ray crystallographic analyses of N-[(2,4-dichlorophenyl)thio]-4-acetyl-2, diphenylphenylaminyl (5c) and N-[(2,4-dichlorophenyl)thio]-4-cyano-2,6-diphenylphenylaminyl (6c) showed that the Ph-N-S-Ph pi-framework is planar, and the 2- and 6-phenyl groups are twisted from the coplane. The ESR studies for 4-8 showed that their hyperfine coupling constants are nearly identical to each other and that the unpaired electron is extensively delocalized onto the anilino benzene ring and the arylthiyl group. The magnetic susceptibility measurements were carried out for five thioaminyl radical crystals and showed that one radical couples ferromagnetically with 2J/k(B) = 16.0 K, and the other four radicals couple antiferromagnetically with 2J/k(B) = -15.6 to -194.6 K or theta = -0.6 to -5.0 K.

  as radical crystals. Their ESR spectra were measured, and the NS and pyridyl nitrogen and anilino meta and pyridyl ortho and para proton hyperfine coupling constants were determined. The spin-density calculations based on the density functional theory were performed by the UBecke 3LYP hybrid method using the STO 6-31G basis set. X-ray crystallographic analyses were performed for three radicals, and
