In Situ Generation of N -Triflylimino-λ 3 -iodanes: Application to Imidation of Phosphines and Catalytic α-Amidation of 1,3-Dicarbonyl Compounds.

We describe the imidation of phosphines and α-amidation of 1,3-dicarbonyl compounds using N -triflylimino-λ 3 -iodane, which is generated in situ from iodosylarene and triflylamide without any other additives. Furthermore, the imino-λ 3 -iodane catalytically generated from an iodoarene precatalyst with oxone and triflylamide promotes α-amidation of 1,3-dicarbonyl compounds, representing the first method catalyzed by imino-λ 3 -iodane.
