New discoveries in chemical research and development in 2021. The transformation of simple hydrocarbons into more complex and valuable products via catalytic C–H bond functionalisation has revolutionised modern synthetic chemistry. 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. Product Details of 288-36-8
In the reactor,Add 90% acetone (volume fraction) 400mL,Stirring,26.2 g of compound (01)Then 34.5 g of potassium carbonate powder was added,0.38 g copper iodide (CuI),1,2,3-triazole.External temperature was raised to 70 ,During the heating process, a large amount of gas is generated,The reaction was stirred at reflux for 5 hours.The reaction mixture was then distilled under reduced pressure at 40 C,When the reaction system is more viscous, add 45mL of water and continue to reduce the steam to distillate without acetone (no acetone in the gas phase). Distilled residue was added 300mL of water, 25% sulfuric acid was added dropwise at room temperature to adjust the pH to 1-2, a yellow suspension.Stir for 30 minutes, filter, and the solids are washed three times with water, 60 mL each. The resulting solid was dried to dryness at 70 C in vacuo,Have pale green solid 19.48g,Compound (1), purity 95.06%.
I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 1H-1,2,3-Triazole help many people in the next few years.
