Synthetic Route of 288-36-8, New discoveries in chemical research and development in 2021. We’ll be discussing some of the latest developments in chemical about CAS: 288-36-8, name is 1H-1,2,3-Triazole, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
To a solution of 2-chloro-5-nitro-3-(trifluoromethyl)pyridine (1.2 g, 6.84 mmol) and 2H-1,2,3-triazole (0.567 g, 8.20 mmol) in anhydrous DMA (5 mL) was added K2CO3 (1.89 g, 13.67 mmol). The reaction mixture was stirred at room temperature for 2 h. The mixture was filtered and washed with ethyl acetate (10 mL*3). The filtrate was concentrated to dryness to give a crude product.
Therefore, this conceptually novel strategy might open impressive avenues to establish green and sustainable chemistry platforms.In my other articles, you can also check out more blogs about 1H-1,2,3-Triazole.
