Use | 4-(trifluoroacetyl) toluene is a trifluoromethyl derivative. Trifluoromethyl compounds show many very unique physical and chemical properties due to their strong electron-withdrawing and highly esterophilic properties. It is also an important pharmaceutical intermediate. |
preparation | in a nitrogen atmosphere, put a polytetrafluoroethylene magnet in a reactor, add 0.4 mmol p-methylbenzene diazo tetrafluoroborate, 0.1 mmol cuprous oxide, 1 mL dichloromethane, 0.8 mmol dimethyl sulfoxide, finally add 1.2 mmol ethyl trifluoropruvate, stir and react at 25°C in a closed system for 16 h, the organic phase was extracted 3 times with ether, 10 mL each time, combined with organic phase, washed 3 times with distilled water, the organic phase was dried with anhydrous magnesium sulfate, filtered, and then spin-evaporated to remove the organic agent; The obtained crude product was eluted by silica gel column chromatography with n-pentane as eluent to obtain 4-(trifluoroacetyl) toluene (separation yield 86%). |
