Related Products of 52222-73-8, These common heterocyclic compound, 52222-73-8, name is 4-(Trifluoromethyl)-1H-pyrazole, 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.
In a nitrogen-purged glove box, a vial, equipped with a TEFLON coated magnetic stir bar, was charged with (oxybis(2,1-phenylene))bis(diphenylphosphine) (1.00 g, 1.86 mmol) and 4-trifluoromethylpyrazole (0.253 g, 1.86 mmol). Toluene (5 mL) was added, followed by mesitylcopper(I) (0.283 g, 1.55 mmol) dissolved in toluene (5 mL). The resulting yellow solution was stirred at approximately 60C for 15 hours. The mixture was cooled and filtered. The white solid was washed with toluene (5 mL) and hexanes (5 mL), and dried to afford the title compound as a white solid (0.785 g).
Statistics shows that 4-(Trifluoromethyl)-1H-pyrazole is playing an increasingly important role. we look forward to future research findings about 52222-73-8.
