The carbonylation of perfluoro-2-R-benzocyclobutenones (R = F, CF3, C2F5, C6F5) in a CO-SbF5 system is accompanied by transformations of the four-membered cycle in the substrate to form polyfluorinated 1H-isochromene derivatives. The reaction of perfluoro-2-R-benzocyclobutenes (R = F, CF3, C2F5) with (CF3CO)(2)O or CF3COOH in a SbF5 medium in a sealed ampule involves formation of polyfluorobenzocyclobutenones and their carbonylation under the reaction conditions.
