Synthetic Route of 61-82-5, New Advances in Chemical Research in 2021. The appropriate choice of redox mediator can avoid electrode passivation and overpotential, which strongly inhibit the efficient activation of substrates in electrolysis. 61-82-5, name is 1H-1,2,4-Triazol-5-amine, molecular formula is C2H4N4, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, below Introduce a new synthetic route.

General procedure: To a mixture of dimedone (1 mmol), aldehyde (1 mmol), 2-aminobenzimidazole or 3-amino-1,2,4-triazole (1 mmol)and nano-SiO2 (15 mol %) in the acetonitrile (5 mL) was stirred for appropriate time (Table 2) at 25-30 C. After the completion of the reaction as indicated by TLC, dichloromethane (CH2Cl2) was added to the solidified mixture and the insoluble catalyst was separated by filtration. Evaporation of the solvent from the filtrate and recrystallization of the solid residue from hot ethanol afforded the pure products in high yields.

The potential utility of systematic synthetic strategy will be applicable to efficient generations of chemical libraries of compounds to find ‘hit’ molecules.Read on for other articles about 1H-1,2,4-Triazol-5-amine, hurry up and to see.

A. Synthesis of OTA: Formation of OTA solution in concentrated sulfuric acid144 g (1.714 mol) of 3-amino-1,2,4-triazole (commercial ATA) are added to 1.2 L of concentrated sulfuric acid (98% by weight commercial concentrated sulfuric acid) precooled to 5 .The mixture is cooled to 5 & lt; 0 & gt; C.150 g (2.174 mol) of sodium nitrite (NaNO2) is gradually added at this temperature of 5 . Do not exceed 10 .At the end of the introduction of sodium nitrite, the reaction medium is gradually heated to 100 under a temperature gradient of 12 / h. When the temperature reaches 100 DEG C (after about 8 hours), the reaction medium is stirred for 2 hours (at the temperature of 100 DEG C).The progress of the reaction is monitored by high performance liquid chromatography (HPLC) after external calibration (using commercial OTA). The OTA yield is measured on samples taken at different temperatures (diluted with water to stop the reaction)

The catalyzed pathway has a lower Ea, but the net change in energy that results from the reaction is not affected by the presence of a catalyst. In my other articles, you can also check out more blogs about 61-82-5
