Abstract

The reaction of perfluorobenzocyclobutene (1 mol) with isomeric tetrafluorobenzenes (2 mol) in an SbF5 medium resulted in the isolation of 1,2-bis(tetrafluorophenyl)perfluorocyclobutene after treatment of the reaction mixtures with HF and of (3,4,5,6-tetrafluorobenzen-1,2-diyl)bis[(tetrafluorophenyl)methanones] after hydrolysis of the reaction mixtures. Along with these products, the reactions with 1,2,4,5- and 1,2,3,4-tetrafluorobenzenes give 4,5,6,7-tetrafluoro-1,3,3-tris(tetrafluorophenyl)-1,3-dihydro-2-benzofuran-1-ols, and the reaction with 1,2,3,4-tetrafluorobenzene affords {2-[bis(2,3,4,5-tetrafluorophenyl)methyl]-3,4,5,6-tetrafluorophenyl}(2,3,4,5-tetrafluorophenyl)methanone.
