OXIDATION CATALYZED BY POLYOXOMETALATE
1217
amounts of the reactants were as follows: 30 mg of catalyst, 1 mL of water, 1 mmol of
substrate, and 5 mmol of hydrogen peroxide. The flask was heated at 90 ꢁC. After
enough reaction time, the solution was extracted by 2 mL of ethyl acetate. The
organic layer was analyzed by gas chromatography. Assignments of products were
1
made by comparison with authentic samples and analyzed by H NMR and 13C
NMR. The aquatic layer was left for the next cycle without addition of fresh catalyst.
