Abstract: Perfluorinated 1-methyl- and 1-ethylbenzocyclobutenes and 2-methyl- and 2-ethylbenzocyclo­butenones reacted with 20% oleum at 150°C to give mixtures of almost equimolar amounts of 3-perfluoroalkyl-4,5,6,7-tetrafluorophthalides and perfluoro-3-hydroxy-3-alkylphthalides. In addition to these products, the reac­tion of perfluoro-2-methylbenzocyclobutenone with oleum at 100°C afforded perfluoro-2-hydroxy-2-methylbenzo­cyclobutenone. The reaction of perfluoro-2-phenylbenzocyclobutenone with oleum produced perfluoro-2-benzoylbenzoic acid, whereas polyfluorobenzocyclobutene-1,2-diols were converted to the corresponding cyclic sulfates.
