Abstrakt: 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. More information can be found in the Communication by Akio Saito et   al. on page   1314 in Issue 11, 2016 (DOI: 10.1002/ajoc.201600383). [ABSTRACT FROM AUTHOR]
