Beschreibung

N-Fluorobenzenesulfonimide fluorinates aromatics, enolates, azaenolates and carbanions in high yield. It is used for diastereoselective fluorination of Li enolates of chiral carboximides, for directed fluorination of ortho-lithiated aromatics and for a review of electrophilic N-F fluorinating agents. Asymmteric fluorinations is effected in the presence of a Pd-BINAP catalyst system at room temperature in an ionic liquid. It is a reagent employed in a palladium-catalyzed enantioselective fluorination of t-butoxycarbonyl lactones and lactams. It is also used in the electrophilic difluorination of dihalopyridines with butyl lithium and in the direct conversion of alcohols to dibenzenesulfonamides with triphenylphosphine. This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
