Synthesis of -(-Benzenesulfonamidobenzal)hydrazine and Its Derivatives

[摘要] Seven new hydrazine derivatives were prepared from N-Aryllsufonylbenzimidoyl chloride. These were: ¥â-(¥á-Benzenesulfonamidobenzal)hydrazine(¥±), ¥â-(¥á-Benzenesulfonamidobenzal)dimethylmethylenehydrazine (¥²), ¥â-(¥á-Benzenesulfonamidobenzal)phenylhydrazine(¥¶), ¥â-(¥á-Benzenesulfonamidobenzal)-4-nitrophenylhydrazine(¥·), ¥â-(¥á-Benzenesulfonamidobenzal)-2,4-dinitrophenylhydrazine(¥¸), ¥â-(¥á-Benzenesulfonamidobenzal)dimethylhydrazine(¥¹), ¥â-(¥á-Benzenesulfonamidobenzal)-p-methylphenylhydrazine (¥¹¥°). The structure of these derivatives were identified by elemental analysis, spectral data and other chemical methods. In general, it was found that the yields of these reactions were significantly improved in polar solvent and by the electron attracting substituents in phenylhydrazine.
