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. HPLC of Formula: C2HBr2N3
15.38 g (67.79 mmol) of 3,5-dibromo-1H-1,2,4-triazole, 24.80 g (203.38 mmol) of phenylboronic acid, 7.83 g (6.78 mmol) of tetrakis(triphenylphosphine)palladium(0), and 18.74 g (135.59 mmol) of potassium carbonate were added to a mixed solution including 170 mL of tetrahydrofuran and 70 mL of water and stirred under reflux. After the reaction was completed, the reaction product was cooled to room temperature, and an aqueous solution layer was removed therefrom by extraction. The resultant was filtered under reduced pressure through silica gel, and the filtrate was concentrated under reduced pressure. The product obtained therefrom was separated by silica gel column chromatography to obtain 9.20 g (yield of 61%) of Intermediate (A). (0267) LC-Mass (Calcd: 221.10 g/mol, Found: M+1=222 g/mol)
The synthetic route of 7411-23-6 has been constantly updated, and we look forward to future research findings.
