Adding a certain compound to certain chemical reactions, such as: 288-36-8, name is 1H-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 288-36-8, Application In Synthesis of 1H-1,2,3-Triazole
Intermediate 14f (0556) 4,5-Dibromo-lH-triazole (0557) Br2 (930 g, 5.82 mol) was added dropwise to a stirred solution of lH-triazole (300.00 g, 4.34 mol, 252.10 mL) in H20 (2 L) at 40 to 45 C. The resulting solution was stirred for a further 1 hour. The precipitate was filtered off and further Br2 (617.28 g, 3.86 mol) was added to the filtrate, then it was kept at 25 C for 16 hours. A second precipitate was filtered off. The combined filtered off solids were washed with water (1 L x 3), dried under vacuum and re-crystallized from MeOH (-400 mL) to give 4,5-dibromo-lH-triazole (Intermediate 14f; 890 g, 90.39% yield) as an off-white solid, m/z (ES+) [M+H]+ (0558) 226/228/230.
