Related Products of 288-36-8, New Advances in Chemical Research in 2021.In classical electrochemical theory, both the electron transfer rate and the adsorption of reactants at the electrode control the electrochemical reaction. 288-36-8, name is 1H-1,2,3-Triazole, molecular formula is C2H3N3, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, below Introduce a new synthetic route.
To a solution of 1H-1,2,3-triazole (0.524 mL, 9.05 mmol) in water (5 mL) at 50 C was added bromine (0.625 mL, 12.13 mmol). The reaction was stirred at 50 C for 90 minutes, whereupon the precipitated product was filtered off. This material was air-dried on the filter. Another aliquot of bromine (0.625 mL, 12.13 mmol) was added to the mother liquor, which was stirred at room temperature overnight. After stirring overnight, collected the solid product by filtration. Filtered off a total of 4,5-dibromo-1H-1,2,3-triazole (1.83 g, 7.91 mmol, 87 % yield) as a white solid. Carried on as-is to alkylation.
