Acetic Acid → 3',5'-Bis-trifluoromethyl-3-methyl-4-nitrobenzophenone

Participants

Reaction Steps

Chromic oxide (IV) (0.41 g) was added to a solution of 4-(3,5-bis-trifluoromethyl-benzyl)-2-methylnitrobenzene (0.3 g) in acetic acid (10 ml) and stirred at room temperature for 1 hour. After the reaction, the reaction solution was extracted with ethyl acetate and washed with water, a saturated sodium bicarbonate solution and a saturated salt solution. After drying over anhydrous magnesium sulfate, the solvent was distilled off and the residue was purified by silica gel column chromatography to obtain 3′,5′-bis-trifluoromethyl-3-methyl-4-nitrobenzophenone (0.3 g).
