摘要

2, 4-Dinitrobenzenesulfonylhydrazine. To a well-stirred solution of 95% hydrazine (6.8 g, 200 mmol) in tetrahydrofuran (400 ml) cooled in a Dry Ice-acetone bath was added 2, 4- dinitrobenzeriesulfonyl chloride (26.6 g, 100 mmol) dissolved in tetrahydrofuran (50 ml). After 30 min the mixture was allowed to warm to ambient temperature. After 15 min the solvent was removed by rotary evaporation and the yellow-colored residue was leached ...
