Versuchsvorschrift
The synthesis was the same as in Example 1 except that about 50 mg of p-toluene sulfonic acid and 50 ml diethoxycyclohexane (from Lancaster) were employed. Under vacuum overnight at about 90° C., some small amount of distilled liquid was discarded, then the temperature was raised up to 120°-130° C. and the 1-ethoxycyclohexene was collected through distillation.
