摘要

The reaction of singlet oxygen with 2 afforded two isomeric dioxetanes 3 and 4 which were decomposed upon heating to the expected dihydronaphthalene derivative 5. Photooxygenation of 2 in the presence of thiourea resulted in the formation of diketone 8 and ketal 7; the later presumably derived from incorporation of the solvent molecule.
