1-(1H-Benzimidazol-2-yl)-2,2-dibromoethanone Use and Manufacturing
The preparation method is to add glacial acetic acid and 2-acetylbenzimidazole to the reaction pot, stir and heat to 80℃, add bromine while stirring under negative pressure, control the reaction temperature at (80±5)℃, and complete the addition. Continue to stir for 1 hour, and then desolvate and react the hydrogen bromide gas generated under reduced pressure for about 1 hour, cool to room temperature, and filter to obtain the product.
2-(Dibromoacetyl)benzimidazole hydrobromide is an intermediate of the fungicide thiabendazole.
