Versuchsvorschrift

In the presence of 0.6 g of para-toluenesulfonic acid, 50 g (0.4 mol) of cyclooctanone and 100 ml (0.9 mol) of isopropenyl acetate were refluxed for 11 hours. The reaction mixture was cooled, stirred with 0.6 g of anhydrous sodium carbonate at room temperature for one hour, left standing overnight, and filtered. The filtrate was distilled under reduced pressure to afford 60 g (91% in yield) of 1-cyclooctenyl acetate having a boiling point of 71° to 73° C./3 mmHg.
