Reaction of perfluorobenzocycloalkenes with SiO2-SbF5 and skeleton transformations of their carbonyl derivatives in SbF5 medium

The reaction of perfluorinated benzocyclobutene and tetraline with SiO 2-SbF5 led to the formation in a high yield of their mono- and further dicarbonyl derivatives. The monocarbonyl derivatives on heating with SbF5 underwent disproportionation into the corresponding perfluorobenzocycloalkenes and diketones. Both mono- and diketones in the SbF5 medium are liable to suffer skeleton rearrangements yielding five- and six-membered oxygen-containing heterocycles and/or products of the opening of the alicyclic fragment of the substrate, and from the perfluorobenzocyclobutenone compounds were also obtained with a number of carbon atoms greater than that of the initial ketone.
