Participants

Reaction Steps

In a 100 ml four-neck flask fitted with a thermometer, a reflux condenser and a stirrer were placed 2-pentylidenecyclopentanone (50 g) synthesized in Reference Example 4 and iodine (5 mg), followed by 3 hours of the reaction at 180° C. The crude product (50 g) was distilled without any treatment using a Claisen distillation apparatus to obtain 39 g of 2-pentyl-2-cyclopentenone (boiling point: 105° C./933 Pa; GC purity: 98.3%).
