Abstract

Abstract A new mode of electron-transfer photooxygenation is shown to occur with the title compound (4). With this electron-rich ethylene derivative, DCA-sensitization in acetonitrile gives rise to the quantitative formation of a cyclic peroxide (5) by cycloaddition of 2 molecules of 4 and 1 molecule of O 2. A mechanism is outlined for this reaction.
