<i>In Situ</i> Generation of <i>N</i>-Triflylimino-λ³-iodanes: Application to Imidation of Phosphines and Catalytic α-Amidation of 1,3-Dicarbonyl Compounds

Abstract

We describe the imidation of phosphines and α-amidation of 1,3-dicarbonyl compounds using <i>N</i>-triflylimino-λ³-iodane, which is generated <i>in situ</i> from iodosylarene and triflylamide without any other additives. Furthermore, the imino-λ³-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-λ³-iodane.
