Abstract

The combination of cyclization and fluorination in a single operation provides a straightforward and efficient approach to fluorinated heterocycles from unsaturated compounds bearing a heteroatom nucleophile. In this study, a metal‐free cycloisomerization–fluorination sequence of N‐propargyl amides catalyzed by an iodine(III) species is reported. The iodine(III) catalyst is in situ generated from iodoarene as a precatalyst with Selectfluor as a fluorinating oxidant in the presence of HF⋅pyridine.
