Trifluoromethanesulfonimide Chemical Properties,Usage,Production
Chemical Properties
light yellow to brown liquid
Uses
1,1,1-Trifluoro-N-((trifluoromethyl)sulfonyl)methanesulfonamide is commonly used as a strong acid to prepare Lewis Acid catalysts. It can also be used to improve efficiency of graphene/silicon Schottky solar cells by chemical doping and as a solvent for recycling battery electrodes.
Uses
Trifluoromethanesulfonimide may be used as a catalyst for the preparation of 1-substituted-1H-1,2,3,4-tetrazoles.
Uses
Trifluoromethanesulfonimide is a strong acid, used in the preparation of highly efficient Lewis acid catalysts.
Application
Trifluoromethanesulfonimide 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.
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.
Synthesis
90076-65-6
82113-65-3
The general procedure for the synthesis of lithium bis(trifluoromethanesulfonyl)imide (HTf2N) from lithium bis(trifluoromethanesulfonyl)imide (LiTf2N) is as follows: LiTf2N is dissolved in concentrated sulfuric acid, followed by sublimation at 70 °C under reduced pressure (10^-3 mbar) to give the HTf2N crude product. This crude product can be further purified. The yield was 90%. The NMR hydrogen spectrum (1H-NMR, D2O) of the product showed: δ 4.77 (s, 1H); the NMR fluorine spectrum (19F-NMR, D2O) showed: δ -79.16 (s, 6F); and the NMR carbon spectrum (13C{19F}NMR, D2O) showed: δ 119.27 (s, 2C).
