New discoveries in chemical research and development in 2021. The dynamic chemical diversity of the numerous elements, ions and molecules that constitute the basis of life provides wide challenges and opportunities for research. 288-36-8, name is 1H-1,2,3-Triazole belongs to triazoles compound, it is a common compound, a new synthetic route is introduced below. Formula: C2H3N3
Bromine (2.2 mL, 43.4 mmol) was added cautiously to a solution of 1H-1,2,3- triazole (2 g, 29.0 mmol) in water (10 mL) at 40°C. The resulting mixture was stirred for 2 hrs at 40°C, then allowed to cool and stood overnight at room temperature. The precipitate was isolated by filtration, washed with water (2×10 mL), and dried in the vacuum oven to give 4,5- dibromo-lH-l,2,3-triazole as a light brown solid. (M+H 225.6; LCMS method 2).
