FORMATION OF A 1,2-DIOXANE BY ELECTRON-TRANSFER PHOTOOXYGENATION OF 1,1-DI(p-ANISYL)ETHYLENE

Article abstract of DOI:10.1016/S0040-4039(00)99835-6

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 O2.A mechanism is outlined for this reaction.
