실험 절차

A slurry of 1-acetyl-3,3-dimethylcyclohexane (156 grams, 1 mole), potassium hydroxide (86 grams, 1.5 moles), and toluene (300 ml) is heated to reflux. Allyl chloride (114 grams, 1.5 moles) is added to the thickened reaction mass whereupon the mass becomes more fluid. The mixture is heated at reflux for 61/2 hours. At the end of this period, the reaction mass is cooled to room temperature, and 500 ml of water is added thereto. The aqueous layer is discarded, and the organic layer is distilled to afford 74 grams of recovered 1-acetyl-3,3-dimethyl hexane, 53 grams of 1-acetyl-3,3-dimethyl-1-(2-propenyl) cyclohexane, and 35 grams of 3,3-dimethyl-1-(4-pentenoyl) cyclohexane.
