Direct fluorination of the pymole ring with electron-withdrawing gtmym, such as, -CHO, -COR, -COOR, -CON&, using xctm difluoride under mild conditions leads to the comsponding flwtopymAcs in 2544% yields. It was found that fluorination takes place only at the u-position of the pyrrole even when the

Pyridine reacts with xenon difluoride to give a mixture of 2-fluoropyridine, 3-fluoropyridine, and 2,6\_difluoropyridine, while 8-hydroxyquinoline is converted to 5-fluoro-8-quinolinol. Aniline and benzylamine react vigorously with XeF, to yield mixtures of monofluoro isomers derived from the parent
