Procedure
In a flask were placed 2-adamantanone (100 mmol), acetylacetonatocobalt [Co(acac)2] (50 mmol), 2,3-butanedione (600 mmol), and acetic acid (100 g). A condenser and an oxygen balloon were attached to the flask, and the mixture in the flask was vigorously stirred at 80° C. for 4 hours. After the completion of the reaction, the reaction mixture was concentrated, was diluted with toluene and washing with water. The resulting organic layer was concentrated, the concentrate was subjected to silica gel column chromatography and thereby yielded the title compound 1-acetyladamantan-4-one in a yield of 21%.
