Interaction of polyfluorobenzocyclobutenes with oleum
View through CrossRef
When perfluorinated 1-methyl- and 1-ethylbenzocyclobutenes, 2-methyl- and 2-ethylbenzocyclobutenones react with 20% oleum at 150°C, 3-perfluoroalkyl-4,5,6,7-tetrafluorophthalides and perfluoro-3hydroxy-3-alkylphthalides are formed in approximately equal proportions. Along with them, perfluoro-2hydroxy-2-methylbenzocyclobutenone was obtained in the reaction of perfluoro-2-methylbenzocyclobutenone with oleum at 100°C. Under the action of oleum, perfluoro-2-phenylbenzocyclobutenone forms perfluoro-2-benzoylbenzoic acid, and polyfluorobenzocyclobutene-1,2-diols form their cyclic sulfates.
