Hexafluoro-3-oxatricyclo[3.2.0.02,4]hept-6-ene (hexafluoro-Dewar-benzene oxide) from the photochemical oxidation of hexafluorobenzene
Abstract
Photochemical oxidation 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.
