Reaction Steps
A mixture of 9.7 g of 1-phenyl-1,4-pentanedione (0.055 mole), 500 ml of water, 15 g of sodium hydroxide and 1000 ml of ethanol was heated under reflux for 4 hours. The mixture was allowed to cool to room temperature and was then neutralized with acid. Ethanol was evaporated. The 3-phenylcyclopent-2-en-1-one formed was recovered by extraction and crystallization.
