Procedure

A solution of 6 grams of 1-vinylcyclooctanol and 50 mg of MTO in 30 ml of benzene was refluxed 18 hours, cooled, washed with aq. potassium carbonate, dried, stripped of solvent and distilled (82-85 deg C./25 mm Hg) to give 3.55 grams of 1-vinylcyclooctene judged to be of 95% purity of NMR analysis; the only impurity was cyclooctanone left over from preparation of the vinyl carbinol.
