摘要：
Electron-accepting substituents at the para position of aryl vinyl sulfides 1 promote the ene reaction with singlet oxygen in competition with the usual [2+2] cycloaddition, while electron-donating substituents afford exclusively dioxetane product, which through their thermally labile nature decompose by C-C cleavage to the corresponding carbonyl fragments.
