Procedure
3.4 g of 1-(5-allylbenzo[d][1,3]dioxol-2-yl)ethanone and 68 mg (1 mol %) of ruthenium (III) acetylacetonate in 20 ml of o-xylene were stirred 2 days at 130° C., then cooled to room temperature. After concentration of the solvent in vacuum, the crude product was purified by flash chromatography on silica gel to give 1.3 g (38%) of a colorless oil.
