Uses
4-Methylbenzenesulfonhydrazide was widely used reagent for the preparation of tosylhydrazones.
Application
p-Toluenesulfonyl hydrazide is used as a reagent for the preparation of tosylhydrazones. It was used to prepare dipyrazolo[1,5-a:4',3'-c]pyridines and 1,2,3-selenadiazole derivatives.

Synthesis

1576-35-8
General procedure for the synthesis of p-toluenesulfonyl hydrazide from p-toluenesulfonyl chloride: general method: preparation of p-toluenesulfonyl hydrazide. A mixed solution of water (300 mL) and hydrazine hydrate (12.5 g; 0.25 mol) was cooled to about 5 °C in an ice-water bath. The reaction temperature was kept below 8 °C while a tetrahydrofuran (50 mL) solution of p-toluenesulfonyl chloride (5.54 g, 0.025 mol) was slowly added under stirring. After the addition was completed, the reaction mixture was continued to be stirred at room temperature for 30 min. Subsequently, the tetrahydrofuran was removed by distillation under reduced pressure. The white solid product was isolated by filtration and washed with cold water (3 x 15 mL). Finally, the product was dried in air overnight to give pure p-toluenesulfonyl hydrazide (4.86 g; 89% yield).
Purification Methods
Dissolve the 4-Methylbenzenesulfonhydrazide in hot MeOH (~1g/4mL), filter through Celite and precipitate the material by adding 2-2.5 volumes of distilled H2O. Dry it in air or in a vacuum. [Fiedman et al. Org Synth Coll Vol V 1055 1973, Beilstein 11 II 66.]
