摘要

Quadricyclane was photooxygenated with singlet oxygen generated under Rose-Bengal- sensitized conditions to a dioxetane, which in turn gave 2-cyclopentene-1, 4-dicarbaldehyde and 5-norbornene-cis-2, 3-exo-diol. For the mechanism to form the dioxetane, an involvement of a [2σ+ 2σ+ 2π] electrocyclic process is proposed.
