Adding a certain compound to certain chemical reactions, such as: 22300-52-3, name is 4,5-Dibromo-2H-1,2,3-triazole, belongs to Triazoles compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 22300-52-3, Quality Control of 4,5-Dibromo-2H-1,2,3-triazole
3- Fluoro-4-nitrotoluene (1367 g, 1 eq.), 4,5-dibromo-2/-/-1 ,2,3-triazole (1999 g, 1 eq.), K2C03 (1340 g, 1.1 eq.) and DMF (1 1 L) is heated to 75 C for 15 h. The reaction mixture is cooled to 22 C and treated with water (18 L). The resulting suspension is filtered, washed with water (4 L). The product is washed with isopropanol (5 L), and dried under reduced pressure to yield a white solid. Yield: 281 1 g, 88%. Purity: 100% a/a (LC-MS method 2). 1H NMR (400 MHz, DMSO) <5: 8.10 (d, J = 8.3 Hz, 1 H), 7.86 (d, J = 1.0 Hz, 1 H), 7.66 (dd, J1 = 0.9 Hz, J2 = 8.3 Hz, 1 H), 2.51 (s, 3 H).
