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.
