Beschreibung

Anwendung

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.
