2,5-二溴-3,4-二硝基噻吩 - Reference Information
| Use | 2,5-dibromo-3, 4-dinitrothiophene is an organic intermediate. 2, 5-dibromo-3, 4-dinitrothiophene can be used to prepare 2, 5-dibromo-3, 4-diaminothiophene, 2, 5-dibromo-3, 4-diaminothiophene is an antibacterial chain extender. |
| preparation | the first step can be obtained by one-step nitration of 2, 5-dibromothiophene: 5mL concentrated sulfuric acid and 5mL fuming sulfuric acid are mixed evenly in a three-mouth flask, then 1mL 2,5-dibromothiophene is added dropwise into the mixed acid, stirred for 30min, cooled down in an ice bath, controlled the temperature below 20 ℃, and the stirring speed is 100r/min; step 2: add 3mL of concentrated nitric acid dropwise to the system under stirring and stir for 5 hours. the reaction process requires ice bath to cool down, control the temperature below 30 ℃, and stir at a speed of 100r /min; Step 3: Pour the reaction product into 300g ice cubes and stir until the ice cubes are completely melted; Then vacuum suction filtration is carried out, and the obtained solid is fully washed and filtered with water. Then recrystallized with methanol and the solid is precipitated, the solution was removed by suction filtration, and 2, 5-dibromo-3, 4-dinitrothiophene was obtained after drying. |
