Research speed reading in 2021. In classical electrochemical theory, both the electron transfer rate and the adsorption of reactants at the electrode control the electrochemical reaction. 1455-77-2, name is 3,5-Diamino-1,2,4-triazole belongs to triazoles compound, it is a common compound, a new synthetic route is introduced below. 1455-77-2
To a methanolic solution (15mL) of 9 3,5-diamino-1,2,4-triazole (0.099g, 1mmol) an equimolar solution of 10 2-chlorobenzaldehyde (0.141g, 1mmol) was added and the mixture was first stirred at room temperature for 30min and then refluxed for 5?6h. The excess of solvent was removed by under reduced pressure using rotavapor and then washed with methanol and recrystallized from dichloromethane – methanol. The resulted product was dried under vacuum. The synthesis scheme alongwith atom number (for assignment only) of the schiff base is presented in Scheme 1 . 2.1.2 12 (E)-N3-(2-chlorobenzylidene)-1H-1,2,4-triazole-3,5-diamine Yield: 0.157g, 71percent; colour: light yellow; m.p: 235?240°C; 1H NMR (delta in ppm DMSO-d6, 500MHz): 12.10 (s, 1H, NHtriazole), 9.36 (s, 1H, H-7), 8.13 (d, 1H, J=7.5Hz, H-3), 7.53 (d, 1H, J=8Hz, H-4), 7.49 (d, 1H, J=8Hz, H-6), 7.43 (t, 1H, J=7.5Hz, H-5), 6.20 (s, 2H, NH2); 13C NMR (delta in ppm DMSO-d6/125MHz): 163.85 (C-8), 157.39 (C-7), 157.10 (C-9), 135.82 (C-2), 133.59 (C-1), 132.93 (C-3), 130.65 (C-6), 128.49 (C-4), 128.27 (C-5); FT-IR (KBr, cm?1): 3322 nuas(NH2), 3233 nu(N?H), 3149 nus(NH2), 2785 nu(C?H), 1651 nu(C=N), 681 nu(C?Cl); MS (ESI) m/z: ([M+H]+) 222.05; Anal.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 3,5-Diamino-1,2,4-triazole, in my other articles.
