The allylic oxidation of 3-(p-methoxyphenyl)-cyclohexene and 3-isopropylcyclohexene

Existing methods for the preparation of LB unsaturated ketones involve the introduction of the double bod into an existing ketone; this has been accomplished, for example, by bromination at the L position followed by dehydrobromination of the bromo ketone. Usually the yields are very poor by this route. Oxidation of olefins has also been reported in some instances to yield L-B unsaturated ketones and it was thought desirable in the present work to further investigate this method.
