Adding a certain compound to certain chemical reactions, such as: 3112-31-0, name is 1H-Pyrazole-3,5-dicarboxylic acid, belongs to pyrazoles-derivatives compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 3112-31-0, name: 1H-Pyrazole-3,5-dicarboxylic acid
The mixture solution of Cu(NO3)2*3H2O (0.2 mmol, 48 mg), 4,4′-bipyridine (0.2 mmol, 31 mg) and pyrazole-3,5-dicarboxylic acid(0.2 mmol, 35 mg) in the deionized water (7 mL), DMF (2 mL)and ethanol (3 mL) was sealed in a 20 mL glass vial. Then, the mixturewas heated at 120° C for 1 day and then slowly cooled down toroom temperature. The blue crystals of 3 were obtained. Yield:10 mg (16percent) based on copper salt Anal. Calcd for Cu5C50H46N14O24:C, 38.88; H, 3.00; N, 12.69. Found: C, 38.79; H, 2.85; N, 13.00percent. FTIRpeaks (KBr, cm-1): 3368br (m(OH)), 1646s (mas(OCO)), 1599s (m(CN)), 1533w, 1481w, 1407w, 1387m (ms(OCO)), 1288s, 1224m,1065w, 1020w, 817w, 806w, 778 m. UV-vis (diffuse reflectance,cm-1): 14407.
