Versuchsvorschrift
In a 30 ml four-neck flask fitted with a thermometer, a reflux condenser and a stirrer were placed 2-(1-hydroxyhexyl)cyclopentanone (20 g) synthesized in Reference Example 2 and iodine (5 mg), followed by 6 hours of the reaction at 150° C. The crude product was purified by column chromatography (hexane/ethyl acetate: 95/5) to obtain 15.3 g of 2-hexyl-2-cyclopentenone (GC purity: 99.1%).
