General description

Bis(trifluoromethane)sulfonimide (TFSI, Tf2N) is utilized as anion species to form 1-ethyl-3-methylimidazolium molten salts. It undergoes acid-base complexation with rod-like poly(2,5-pyridine) to afford highly-ordered lamellar self-assemblies in the hydrated films.

Application

Bis(trifluoromethane)sulfonamide may be used in the following studies:
  • As catalyst during the polymerization of octamethylcyclotetrasiloxane in the presence of hexamethyldisiloxane.
  • As efficient catalyst in the synthesis of various non-reducing disaccharides, via ketopyranosylation of 2,3,4,6-tetra-O-benzyl-1-C-methyl-D-hexopyranoses.
  • Starting material for preparing the N-fluoro derivative, a reactive fluorinating agent.
  • As a component of solid polymer electrolytes.
