  • Title: Synthesis of 1,3-dialkyl-1,2,3-triazolium ionic liquids and their applications to the Baylis-Hillman reaction.
    Author: Jeong Y, Ryu JS.
    Journal: J Org Chem; 2010 Jun 18; 75(12):4183-91. PubMed ID: 20499940.
    Abstract:
    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][PF(6)] could be suppressed in the reaction of [bmTr][PF(6)] or [bmTr][NTf(2)]. 1,3-Dialkyl-1,2,3-triazolium ionic liquids are chemically inert under basic conditions and more suitable media for the reactions involving bases than the common 1,3-dialkylimidazolium ionic liquids.
