Synthetic Route of 1347736-74-6, 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. 1347736-74-6, name is 4,7-Dibromo-5-fluoro-2,1,3-benzothiadiazole belongs to bromides-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below.
the 4,6-dibromo-5-fluorobenzo [c] [1, 2, 5] thiadiazole (2.00g, 6 . 41 mmol) and ethanol (50 ml) is added to the three-hole and round-bottom flask cooled to 0 C. In slowly adding Na[BH4] (4.6g, 0 . 12 mol) later, the reaction mixture is stirred at room temperature overnight. After removing the volatile substance, the 100 distilled water added to the reaction mixture, then the mixture is extracted with ethyl ether, salt water cleaning, and the anhydrous Na2SO4dry. Removing volatile substances from the extract to obtain a light brown powder A (1.20g, 66%).
The synthetic route of 4,7-Dibromo-5-fluoro-2,1,3-benzothiadiazole has been constantly updated, and we look forward to future research findings.
