Synthetic Route of 288-36-8, New Advances in Chemical Research in 2021.In classical electrochemical theory, both the electron transfer rate and the adsorption of reactants at the electrode control the electrochemical reaction. 288-36-8, name is 1H-1,2,3-Triazole, molecular formula is C2H3N3, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, below Introduce a new synthetic route.
To 2H-1,2,3-triazole (2.0 g, 29 mmol) in DMF (145 ml) was added NaH (1.16 g, 29 mmol, 60% inmineral oil) at RT and the mixture was stirred for 1h. After cooling to 0C, 2-chloro-1-fluoro-4-nitrobenzene (4.6 g, 26.1 mmol) was added and the reaction mixture was stirred at 0C for 1.5h,then at RT for 1.5h. The mixture was quenched with water and extracted with ethyl acetate. Theorganic phase was washed with water and brine, dried over Na2SO4, filtered and concentrated.The crude product was purified by chromatography on silica gel (heptane/AcOEt: 90/10 to 50/50)to afford 2-(2-chloro-4-nitrophenyl)-2H-1,2,3-triazole.
In the meantime we’ve collected together some recent articles in this area about 288-36-8 to whet your appetite. Happy reading!
