The title compounds were synthesized CF2: addition to the respective methylenecyclopropanes. The hexafluorospiropentane thermally rearranges to 2,2,4,4-tetrafluoro-1-(difluoromethylene)cyclobutane in competition with CF2: extrusion, whereas perfluorospiropentane decomposes exclusively by CF2: extrusion.
