When pentafluoropyridine and heptafluoro-quinoline and -isoquinoline react with hydrogen halides in tetrahydro-thiophen dioxide, replacement of fluorine ortho and para to ring nitrogen by the other halogen occurs. The order of reactivity is heptafluoroquinoline ⋙ heptafluoroisoquinoline > pentafluoropyridine. Reaction with heptafluoro-quinoline occurs at room temperature with substitution first at
