Reference of 342789-81-5,Some common heterocyclic compound, 342789-81-5, name is 1-Butyl-3-methylimidazolium methanesulfonate, molecular formula is C9H18N2O3S, 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.
5.3-1-Butyl-3-methylimidazolium N-trifluoro-sulfonamidate [BMI.(CF3SO2)2N]A mixture formed by 1,3-dimethyl imidazolium methanesulfonate (BMI.CH3SO3) (4.26 g; 18.2 mmol), lithium N-trifluoro sulfonimidate (5.47 g; 19.1 mmol) and water (10.0 mL) was stirred at room temperature for 45 minutes. The resulting mixture, made up by two phases, was extracted with dichloromethane (3×15 mL). The combined organic extract was washed with water (1×20 mL) and dried with anhydrous sodium carbonate. The solvent was evaporated under vacuum and heated (80 C.), which produced the desired ionic liquid BMI.(CF3SO2)2N (7.33 g. 96% yield).
The synthetic route of 342789-81-5 has been constantly updated, and we look forward to future research findings.
