The Uses of 1-Butyl-1-methylpyrrolidinium trifluoromethanesulfonate

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.

Preparation

First, the N, N'-butylmethylpyridinium chloride and potassium trifluoromethanesulfonate are mixed in acetone and reacted for 24 h. The reaction solution is filtered to remove solid impurities. Finally, acetone in the solution is removed by distillation and purified to obtain 1-Butyl-1-methylpyrrolidinium trifluoromethanesulfonate. 1-BUTYL-METHYLPYRROLIDINIUM TRIFLUOROMETHANESULFONATE
