Novel 1,3-dialkyl-1,2,3-triazolium ionic liquids were synthesized via click reactions using 1-trimethylsilylacetylene and alkyl azides and were efficient reaction media for the Baylis−Hillman reaction. The problems associated with deprotonation of the C-2 hydrogen of [bmim][PF6] could be suppressed in the reaction of [bmTr][PF6] or [bmTr][NTf2]. 1,3-Dialkyl-1,2,3-triazolium ionic liquids are chemically
