Application

1-Butyl-1-methylpyrrolidinium trifluoromethanesulfonate ([BMPy][OTf]) is an ionic liquid that can be used as a solvent in:
  • Rhodium-catalyzed regioselective hydroformylation reactions.
  • Direct asymmetric aldol condensation reaction.
  • Desulfurization of fuels.
  • Nucleophilic aromatic substitution reactions.

([BMPy][OTf]) can also be used as an electrolyte in supercapacitor applications.
