SYNTHESIS OF LARGE RING DIENES AND THEIR REACTION WITH MALEIC ANHYDRIDE

Abstract

Cyclotetradecanol–on–2 was dehydrated in the gas phase to cyclotetradecen–one–3. The latter was reduced with lithium aluminum hydride to cyclotetradecen–ol–3, which was converted by dehydration to cyclotetradecadiene. This compound gave with maleic anhydride 3-6-decamethylene tetrahydrophthallic anhydride. The same series of reactions was performed in the cyclooctadecane series.
