The title reactions were achieved in the presence of a fluoride anion: the reaction of perfluoro- (5,6-dihydro-2H-1,4-oxazine) (1) with an equal amount of trimethyl (pentafluorophenyl) silane (3) provided not only a monosubstituted compound but also di and trisubstituted compounds, while the reaction of 1 with three molar excess of 3 only gave trisubstituted compounds. A significant heterocyclic ring effect was observed: the reaction of perfluoro- (3,4-dihydro-2H-pyrrole) (2) with 3 mainly gave a dimer of 2 with a trace amount of a monosubstituted compound.
