(S)-Pyrrolidin-2-ylmethyl-1,2,3-triazolium salts were synthesized as new task-specific ionic liquids via click reaction and alkylation. They serve as excellent recyclable catalysts in enantioselective Michael additions to nitrostyrenes in excess of carbonyl compounds as reactant and as solvent providing high yields and stereoselectivities.
