The novel 1,3-dialkyl-1,2,3-triazolium ionic liquids [bmTr][PF6] and [bmTr][NTf2] are chemically inert under basic conditions and more suitable media for reactions involving bases than common 1,3-dialkylimidazolium ionic liquids such as [bmim][PF6]. [bmTr][PF6] and [bmTr][NTf2] were efficient reaction media for the Baylis-Hillman reaction.
