Room Temperature Ionic Liqiuds-New Choline Derivatives

Pernak J., Chwała P., Syguda A.

Polish Journal of Chemistry

2004

Vol. 78 / nr 4

539-546

New room temperature ionic liquids - choline derivatives were prepared by Menschutkin reaction with alkyl chloromethyl ethers and anion changed to bis(trifluoromethylsulfonyl) amide ion. The newly obtained butoxymethyl(2-hydroxyethyl)dimethylammonium bis(trifluoromethanesulfonyl)amide was successfully tested as a solvent for O-acylation in two-phase reaction system. The ionic liquid-catalyst system was recycled and reused.
