Abstract
The synthesis of new 6-perfluoroalkylated 1,2,3-triazolo-1,4-oxazine ethers and thioethers as fused exo-heterobicyclic compounds was achieved from terminal perfluoroalkyl oxiranes by azide ion ring opening and propargylation reactions followed by a quick and spontaneous 1,3-dipolar intramolecular cycloaddition reaction.
