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. 288-36-8
Step A: A solution of lH-l,2,3-triazole (1.0 g, 14.5 mmol), methyl iodide (3.1 g, 21.7 mmol) and K2CO3 (4.0 g, 28.9 mmol) in THF (15 mL) was stirred at room temperature for 3 hours. EtOAc (20 mL) and H20 (10 mL) were added, separated. The solvent was concentrated under vacuum. The crude residue was purified by silica gel chromatography eluting with 10% MeOH/DCM to afford l-methyl-lH-l,2,3-triazole (860 mg, 10.4 mmol, 71% yield) as yellow oil.
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.
