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
新型的1,3-二烷基-1,2,3-三唑鎓离子液体是通过使用1-三甲基甲硅烷基乙炔和叠氮化物的点击反应合成的,是Baylis - Hillman反应的有效反应介质。在[bmTr] [PF 6 ]或[bmTr] [NTf 2 ]的反应中,可以抑制与[bmim] [PF 6 ]的C-2氢的去质子化有关的问题。1,3-二烷基-1,2,3-三唑鎓离子液体在碱性条件下是化学惰性的,并且比普通的1,3-二烷基咪唑鎓离子液体更适合于涉及碱的反应介质。
