## Abstract Hexafluoropropene reacts with aromatic azine __N__โ€oxides under mild conditions to produce fluorides of 2โ€heteroarylperfluoropropionic acids. The reaction proceeds as 1,3โ€dipolar cycloaddition followed by spontaneous scission of the N๏ฃฟO bond in the isoxazolidine ring and elimination of
