Reaction of singlet oxygen with alkenylidenecyclopropanes: Implication for a peroxyallyl intermediate

Akasaka, Takeshi,Misawa, Yoshihisa,Ando, Wataru

, p. 1173 - 1176 (1990)

Photosensitized oxygenation of adamantenylidenecyciopropanes (1) gave either the corresponding oxetanones (2a-c) or the cyclic ketones (4 and 5) depending on the substituent on the cyclopropane ring in addition to adamantanone. The results are rationalized in terms of initial formation of a perepoxide followed by that of a peroxyallyl intermediate.
