Application

4-(Acetylamino)phenyl]imidodisulfuryl difluoride (AISF) is a shelf-stable, crystalline reagent for synthesis of fluorosulfates and sulfamoyl fluorides via reaction with phenol and amine nucleophiles. A convenient alternative to the toxic sulfuryl fluoride gas traditionally required for installation of the valuable -SO2F functional group, the solid reagent AISF will find wide utility in preparation of synthetic precursors as well as chemical biology, polymer chemistry, cross-coupling, and deoxyfluorination applications.

The design, synthesis, and application of [4-(acetylamino)phenyl]imidodisulfuryl difluoride (AISF), a shelf-stable, crystalline reagent for the synthesis of sulfur(VI) fluorides, is described. The utility of AISF is demonstrated in the synthesis of a diverse array of aryl fluorosulfates and sulfamoyl fluorides
