In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 7411-23-6, name is 3,5-Dibromo-1H-1,2,4-triazole belongs to Triazoles compound, it is a common compound, a new synthetic route is introduced below. name: 3,5-Dibromo-1H-1,2,4-triazole
3,5-dibromo-1H-1,2,4-triazole (419 mg, 1.85 mmol) was added to a solution of phenylboronic acid (300 mg, 2.46 mmol), pyridine (0.2 mL, 2.46 mmol), copper(II) acetate (335 mg, 1.85 mmol) and 3 A molecular sieves in dry DCM (8 mL) and stirred at 25 C overnight. Upon completion monitored by LC/MS, sat. NH4Cl (20 mL) was added to the reaction mixture which was then washed with water, the organic layers were then combined and concentrated. The crude product was purified by flash column chromatography eluting with 15-50% EtOAc in Pet. Ether to give 3,5-dibromo-1-phenyl-1,2,4-triazole (454 mg, 1.50 mmol, 60% yield). LC-MS (ES+, Method A): 1.74 min, m/z 304.0 [M+H]+
The synthetic route of 7411-23-6 has been constantly updated, and we look forward to future research findings.
