Research speed reading in 2021. The prevalence of solvent effects in heterogeneous catalysis in condensed media has motivated developing quantitative kinetic. 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
A mixture of 2,3-difluorobenzonitrile (4.0 g, 28.8 mmol), 2H-1 ,2,3-triazole (1 .9 g, 28.8 mmol) in DMF (85.0 mL) and K2CO3 (7.9 g, 57.5 mmol) were heated to 125 C for 1 .5 h. After cooling to rt, water was added and the mixture extracted with EtOAc (2 X). The combined organics were washed with brine and dried (Na2SO4). Purification via FCC (10-100% EtOAc in hexanes) gave two products. 3-Fluoro-2-(2H-1 ,2,3-triazol-2- yl)benzonitrile (1 .6 g, 29%), 1H NMR (CDCI3): 7.99 (s, J = 6.6 Hz, 2H), 7.67 – 7.63 (m, 1 H), 7.61 – 7.53 (m, 2H), 7.26 (s, 6 H) and 3-fluoro-2-(1 H-1 ,2,3-triazol- 1 -yl)benzonitrile (2.0 g, 38%) 1H NMR (CDCI3): 7.97 (dd, J = 4.4, 2.8 Hz, 1 H), 7.95 (d, J = 1 .2 Hz, 1 H), 7.70 (tt, J = 5.7, 2.8 Hz, 1 H), 7.65 (td, J = 8.1 , 4.9 Hz, 1 H), 7.62 – 7.57 (m, 1 H).
In conclusion, we affirm that quantitative kinetic descriptions of catalytic behavior continue to serve as an indispensable tool to navigate research efforts intended to model. Read on for other articles about 288-36-8.
