Abstract: Oleyl ester of p-benzoylbenzoic acid (I) was irradiated in carbontetrachloride. The triplet state of benzophenone served to abstract hydrogen; intramolecular to, but structurally remote from the excited carbonyl. the photolysis produced a diradical which cyclized predominantly at the ketyl position to yield the lactone (II). Compound II was dehydrated to III, which was then ozonized to IV and v.The distribution of oxidation sites was determined by gas liquid chromatographic analysis of IV.Retention time wascompared with those of standard keto acids. Oxidation was distributed over seven carbons with 88.6\ over three centers C-12, C-14, C-15, and a maximum oxidation of 37.7% at carbon C-12.
