Application of 7411-23-6, New Advances in Chemical Research in 2021. Redox catalysis has been broadly utilized in electrochemical synthesis due to its kinetic advantages over direct electrolysis. 7411-23-6, name is 3,5-Dibromo-1H-1,2,4-triazole, molecular formula is C2HBr2N3, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, below Introduce a new synthetic route.
A solution of 3,5-dibromo-1H-1,2,4-triazole (250 mg, 1.1 mmol), 2-bromoethyl methyl ether (0.17 mL, 2.2 mmol) and triethylamine (0.46 mL, 3.3 mmol) in DMA (5 mL) was stirred at 55 C for 18 h. The reaction mixture was filtered and the solvent removed in vacuo. The product was purified via silica column chromatography eluting with 0-100% EtOAc in Pet. Ether to yield 3,5-dibromo-1-(2-methoxyethyl)-1,2,4-triazole (260 mg, 0.91 mmol, 83% yield) as a colourless oil. UPLC-MS (ES+, Method A), 1.34 min, m/z 285.9 [M+H]+.
By the way, if you are interested in learning more fun chemistry with your kids, get your hands into one chemistry set now, and start enjoying the best part of chemistry: experiments about 3,5-Dibromo-1H-1,2,4-triazole.
