Vapour-phase ultraviolet irradiation of hexafluorobenzene in the presence of oxygen slowly yields hexafluoro-3-oxatricyclo[3.2.0.02,4]hept-6-ene (2) (10%). The CFCF bond in 2 adds (yields of adducts given) the dienes; cyclopentadiene (74%), furan (61%) and 2,5-diphenylisobenzofuran (59%); benzonitrile oxide (58%); chlorine (59%) and bromine (71%) photochemically. Heptene 2 isomerises thermally to

Photochemicaloxidation of hexafluorobenzene in the vapour phase yields the title compound, which undergoes thermal rearrangement into hexafluorocyclohexa-2,4-dienone and two acid fluorides, attack by diethyl ether at the oxiran ring, and cycloaddition to its CC double bond.
