ABSTRACT:
A method is provided for oxidatively cleaving .alpha.,.beta.-unsaturated cyclic ketones, such as isophorone, with an oxidizing agent, for example, ozone, and thereafter recovering the resulting keto acid. In instances where ozone is used, an aqueous hydroperoxide and phase transfer catalyst can be used to recover the keto acid. Dione cyclics, for example, dimedone, can be obtained by direct dehydration of the keto acid.
