Glycosyl trichloroacetimidates react smoothly in the presence of trimethylsilyl trifluoromethanesulfonate
as a catalyst with a variety of alcohols and monosaccharides in [bmim]PF6 (1-butyl-3-methylimidazolium hexafluorophosphate) as a solvent to afford the corresponding
glycosides or disaccharides.
