General description

1-Butyl-3-methylimidazolium trifluoromethanesulfonate [bmim][OTf] is a versatile ionic liquid commonly used in synthetic chemistry.

Application

[bmim][OTf] can be used as:       
  • A glycosylation promoter in the synthesis of oligosaccharides from thiophenyl and trichloroacetimidate glycoside donors.      
  •  A solvent for the extraction of sulfur and nitrogen containing aromatic organic compounds from aliphatic hydrocarbons.
  •   A reagent in the preparation of ion-conductive polymeric membranes.        
  • A dopant in the synthesis of poly (ethyl methacrylate) based polymer electrolytes to increase the ionic conductivity.
  •  A reaction medium to synthesize aryl ketones by Friedel–Crafts benzoylation of aryl compounds by using bismuth triflate as a catalyst.
