Versuchsvorschrift

A mixture of 1-acetyl-3,3-dimethylcyclohexane (156 grams, 1 mole) sodium hydroxide (60 grams, 1.5 moles), methallyl chloride (135 grams, 1.5 moles) and triethylamine (10 grams) is stirred and heated at 80°-84° C. for 12 hours. The reaction mass is cooled to room temperature. Water is added with stirring, and the aqueous layer is discarded. The organoc layer is distilled to afford 1-acetyl-3,3-dimethylcyclohexane (62.4 gm), 1-acetyl-3,3-dimethyl-1-(2-methyl-2-propenyl)cyclohexane (80 gm), (NMR spectrum, FIG. 1; IR spectrum, FIG. 2), and 3,3-dimethyl-1-(4-methyl-4-pentenoyl)cyclohexane (8 gm).
