As an important bridge between the micro and macro material world, chemistry is one of the main methods and means for humans to understand and transform the material world. 7411-23-6, name is 3,5-Dibromo-1H-1,2,4-triazole, molecular formula is C2HBr2N3, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, below Introduce a new synthetic route.
To a suspension of NaH (60% in mineral oil, 387.9 mg, 9.7 mmol) in THF (20 mL) at 0C is added a solution of A6a (2.0 g, 8.8 mmol, Matrix) in THF (20 mL). The reaction mixture is allowed to warm to RT and is stirred for 30 mm. It is then cooled again to 0C and A6b (1 .9 mL,10.6 mmol, Combi Blocks) is added. The reaction mixture is stirred overnight at RT and diluted with EtOAc (50 mL). The organic layer is washed with water (30 mL) and brine (30 mL), dried over MgSO4, and filtered. The filtrate is concentrated to give A6c which is used without further purification.
By the way, if you are interested in learning more fun chemistry with your kids, get your hands into one chemistry set now, and start enjoying the best part of chemistry: experiments about 3,5-Dibromo-1H-1,2,4-triazole.
