2034-22-2 - Reference Information
| Application | 2,4, 5-tribromoimidazole is an organic intermediate, which can be obtained after imidazole bromide. 2,4, 5-tribromoimidazole can be debrominated to obtain 4,5-dibromoimidazole. |
| preparation | imidazole (29.24g,0.43mol), sodium acetate (317.34g,3.87mol) and acetic acid (150ml) were added to the three-mouth bottle. bromine (65ml,1.28mol) dissolved in acetic acid (100ml) was slowly dripped at room temperature through a constant pressure separatory funnel, and the temperature was controlled not to exceed 40 ℃, stirring at room temperature for 3 hours, the reaction solution is poured into 1.5L of water, solids are precipitated, filtered, solids are washed with water, and dried to obtain compound 2,4, 5-tribromimidazole (120g, yield 92%), mass spectrometry: 305(M H). |
