Abstract
Reactions of N-pyrrolylpotassium with fluorinated electrophiles yielded N-substituted pyrroles containing polyfluoroalkyl, polyfluoroalkenyl, polyfluoroalkylsulfonyl, and polyfluoroaryl substituents. N-Polyfluoro-substituted pyrroles did not isomerize at ≥100 °C; they were found to be reactive in [4+2] cycloaddition reactions with perfluorobut-2-yne.
