| Abstract: | A reaction of perfluoro-1-methylbenzocyclobutene with pentafluorobenzene in SbF5 medium followed by treating the reaction mixture with water gave rise to perfluoro-1-methyl-1-phenylbenzocyclobutene, perfluoro-1-methyl-2-phenylbenzocyclobutene, 2-hydroxyperfluoro-1-methyl-2-phenylbenzocyclobutene, and also to small amounts of 1-(2-trifluoromethyltetrafluorophenyl)-1-pentafluorophenyl-2,2,2-trifluoroethane, and perfluoro-1-(2-methylphenyl)-1-phenylethylene. In a crystal of (E)-2-hydroxyperfluoro-1-methyl-2-phenylbenzocyclobutene for a dimer molecular pair a  -stacking interaction between pentafluorophenyl groups was found. |
