実験手順

A slurry of potassium hydroxide (84 grams, 1.5 moles), 1-acetyl-3,3-dimethyl) cyclohexane (156 grams, 1 mole), dibenzo-18-crown-6 (3 grams) having the structure: ##STR31## produced by the Aldrich Chemical Company of Metuchen, New Jersey, and toluene (150 ml) is heated to reflux whereupon the reaction mass thickens. The mass is cooled to 70° C., and allyl chloride (114 grams, 1.5 moles) is added thereto rendering the reaction mixture more fluid. The reaction mixture is heated at reflux for an additional 9 hours whereupon the mass is cooled, and water is added. The aqueous layer is added, and the organic layer is distilled for afford 24 grams of 3,3-dimethylcyclohexane, 48 grams of 1-acetyl-3,3-dimethyl-1-(2-propenyl)cyclohexane, and 90 grams of nonvolatile material.
