N2 - A simple gram-scale method for the preparation of esters and dialkylamides of 2-(fluoro/iodo)-2H-azirine-2-carboxylic acids via the halogen exchange (Halex) reaction of 2-bromo-substituted analogues is reported. The method operates with inexpensive and safe reagents, Bu4NF and potassium iodide, providing high product yields. Alternatively, 2-fluoro-2H-azirine-2-carboxylates can be prepared from 2-iodo- and 2-chloro-analogues. The latter compounds can be obtained in practically quantitative yield by treating the 2-iodo- and 2-bromo-2H-azirine-2-carboxylic esters with Bu4NCl.
