N-Fluorobenzenesulfonimide, 97%

Product Code. 11308855

Brand: Thermo Scientific Alfa Aesar L13955.03

Description

CAS: 133745-75-2 | C12H10FNO4S2 | 315.333 g/mol

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.
