Abstract

Photooxidation of several mesoionic compounds gave ring cleavage products, some of which were apparently formed via the endoperoxides of the mesoionic rings. Photooxidation of a Δ 2-oxazolin-4-one and a Δ 2-thiazolin-4-one gave the corresponding 4, 4′-bisoxa-and bisthiazolinone in dichloromethane, whereas the former gave benzamide in dimethylformamide.
