Reaction Conditions:
with oxygen;copper(II) acetate monohydrate;cobalt(II) diacetate tetrahydrate in water at 70; under 760.051 Torr; for 1 h;
Steps:
15 Example 15 Preparation of p-trifluoromethylbenzoic acid by oxidation of p-trifluoromethylbenzaldehyde
Under atmospheric pressure oxygen, water (2mL), p-trifluorobenzaldehyde (1mmol), Cu(OAc)2· H2O (0.003mmol, 0.3% mole fraction) and Co(OAc)2· 4H2O (0.003 mmol, 0.3% mole fraction) was added to a 15 mL glass reaction tube, and an oxygen balloon was connected.The reaction tube was placed in an oil bath heated to 70°C in advance and stirred for 1 hour. After the reaction was completed, the temperature was lowered, the crude product solid was separated by centrifugation, and then ultrasonically washed with 3 mL of water, centrifuged and dried to constant weight to obtain the target product. The separation yield was 99 %.
