Versuchsvorschrift

In an ambient pressure oxygen atmosphere, 29.2 mg of 4-phenyl-but-3-ene-2-ol and 33.9 mg of the platinum catalyst obtained in Example 1 were agitated for fifteen hours at 60° C. in 2 ml of water. The reaction mixture was subsequently extracted using ethyl acetate, and the organic layer was dried using magnesium sulfate, filtered and concentrated to obtain 25.2 mg (87% yield) of benzalacetone. The reaction equation and the analytical results of the product are shown below.
