Conclusions
Upon reaction of perfluoro-3-methylindene and perfluoro-1-methyleneindane with hexafluoropropylene oxide at 225°C the corresponding cyclopropane derivatives are formed: perfluoro-la-methyl-1,1a,6,6a-tetrahydrocycloprop[a]indene and perfluorospiro[indane-1,1′-cyclopropane], which are transformed during thermolysis in the presence of bromine into 1-bromo-2-difluorobromomethylperfluoro-1-methylindane and 1-bromo-1-(2-bromotetrafluoroethyl)perfluoroindane respectively, and in the absence of bromine into the starting olefins.
