Photosensitized oxygenation of adamantylidenecyclopropanes gave either the corresponding 4-methylene-1,2-dioxolane or lactone and cyclic ketone depending on the substituent on the cyclopropane ring. The results are rationalized in terms of initial formation of a perepoxide intermediate followed by that of an allylic cation-type zwitterion or a carbonyl oxide, respectively.
