Yield:455-38-9 98%
Reaction Conditions:
with oxygen;copper(II) acetate monohydrate;cobalt(II) diacetate tetrahydrate in water at 70; under 760.051 Torr; for 12 h;
Steps:
9 Example 9 Preparation of m-fluorobenzoic acid by oxidation of m-fluorobenzaldehyde
Under atmospheric pressure oxygen, water (2 mL), m-fluorobenzaldehyde (1 mmol), Cu(OAc)2·H2O (0.003 mmol, 0.3% mole fraction) and Co(OAc)2·4H2O (0.003mmol, 0.3% mole fraction) was added to a 15mL glass reaction tube, and an oxygen balloon was connected.The reaction tube was placed in an oil bath heated to 70°C in advance to stir the reaction for 12 hours. After the reaction was completed, the temperature was lowered, the crude product solid was centrifuged, and then ultrasonically washed with 3 mL of water, centrifuged, and dried to constant weight to obtain the target product. The separation yield was 98 %.
