Yield:1576-35-8 94%

Reaction Conditions:

with carbazic acid in neat (no solvent) at 100; for 5 h;Green chemistry;

Steps:

17

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 17.21 g of 4-methylbenzenesulfonic acid was used instead of adipic acid. As a result of the analysis, the product was 4-methylbenzenesulfono-hydrazide, the selectivity was 96% or more, and the yield was 94%. Yield: (17.48 g, 94%);
