Research speed reading in 2021. The prevalence of solvent effects in heterogeneous catalysis in condensed media has motivated developing quantitative kinetic. 16681-65-5, name is 1-Methyl-1H-1,2,3-triazole belongs to triazoles compound, it is a common compound, a new synthetic route is introduced below. Recommanded Product: 1-Methyl-1H-1,2,3-triazole
The title compound was prepared according to No. WO2008 / 135826 International Patent Application Publication. In 1-methyl -1H-1,2,3- triazole (1.0g, 12.0 mmol, prepared according to International Patent Application No. 2008098104) 50 mL 2-neck flask containing, by the addition of THF (45 mL) , colorless solution was cooled to -40 . Then, by adding dropwise the (2.5 M, 4.8 mL, 12.0 mmol in hexane) n-BuLi, to give a dark reddish brown viscous solution. The mixture was stirred for 45 minutes at -30 to -20 in the following, was introduced into a pure DMF (3mL, 38.5 mmol) at -10 . The mixture was allowed to warm to room temperature, after stirring for 60 minutes, poured into water. Extract the aqueous portion with EtOAc (4 × 50 mL), the combined organics washed with brine, dried with MgSO4, filtered, and concentrated. The aqueous portion was extracted with DCM (3 × 50 mL) station, and dried as described above. The combined organics were concentrated to give a light brown oil The UV activity much higher than the starting material. DCM-25% CH3CN, according to TLC or of from 25% EtOAc-DCM, showed the product has a slightly higher Rf than the starting material. (With 100% DCM, 25% CH3CN-DCM increased) by silica gel chromatography on to give the title compound as a colorless oil.
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 16681-65-5.
