4,4'-Oxybis(benzenesulfonyl hydrazide) synthesis

Yield:80-51-3 91%

Reaction Conditions:

with carbazic acid in neat (no solvent) at 100; for 5 h;Green chemistry;Reagent/catalyst;Temperature;Solvent;

Steps:

22
General procedure: 7.6 g (100.0 mmol) of solid hydrazine (H3N + NHCO2-) and adipic acid (7.3 g, 50.0 mmol) were mixed in a mortar without a solvent for 10 minutes and stirred at 100 ° C for 5 hours. To confirm the structure and composition of the product produced in this process and analyzed using 400 MHz NMR (nuclear magnetic resonance) and elemental analysis) .As a result of the analysis, the product was adipohydrazide (C6H14N4O2), the conversion rate was 96% or more, and the yield was 95% or more. Yield (8.27 g, 96% or more); The product was obtained in the same manner as in Example 1 except that 16.66 g of 4,4'-oxydibenzenesulfonic acid was used instead of adipic acid. As a result of analysis, the product was 4,4'-oxydibenzenesulfono-hydrazide, the selectivity was 98% or more, and the yield was 97%. Yield (17.38g, 97%). The product was obtained in the same manner as in Example 20 except that 9.19 g of 4,4'-oxydibenzene-1-sulfonyl chloride was used instead of 4,4'-oxydibenzene-1-sulfonyl chloride. As a result of the analysis, the product was 4,4'-oxydibenzenesulfono-hydrazide and hydraziniumchloride, and 4,4'-oxydibenzenesulfonic acid hydrazide The selectivity of the zeol was 96% or more, and the yield of 4,4'-oxydibenzenesulfono hydrazide after removal of hydrazinium chloride by using water was 91%.
