Molecular formula：C12H10FNO4S2
Structural formula:

CAS Code：133745-75-2
Molecular Wt: 315.35
Application:
To be used as a fluidizer, chemical react to electron-rich aromatic compounds, silyl enol ethers, enol lithium.

As reagent employed in a palladium-catalyzed enantioselective fluorination of t-butoxycarbonyl lactones and lactams.Also used in the electrophilic difluorination of dihalopyridines with butyl lithium and in the direct conversion of alcohols to dibenzenesulfonamides with triphenylphosphine.  
  Stable, easy-to-handle, crystalline material which readily transfers F+ to enolates and carbanions.
