The photooxygenation of three homoallylic substrates, the γ,δ-unsaturated ketone 1a, nitrile 2a, and the γ,δ-unsaturated ester 3a was investigated in homogeneous solution and in microemulsion (for 1a). Two secondary reaction pathways were detected for the allylic hydroperoxides of type b and c, respectively. The cyclization reactions of 1b and 2b to the 1,2-dioxanes 1d and 2d followed well-known reaction
