Applications
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.

Solubility
Very soluble in acetonitrile, dichloromethane or THF and less soluble in toluene.

Notes
Store in cool place. Keep container tightly closed in a dry and well-ventilated place. Incompatible with oxidizing agents.
