1,2,3-triazolium ionic liquids

摘要

The present invention relates to compositions of matter that are ionic liquids, the compositions comprising substituted 1,2,3-triazolium cations combined with any anion. Compositions of the invention should be useful in the separation of gases and, perhaps, as catalysts for many reactions.

1. An Ionic Liquid composition comprising: wherein R1 is a vinyl group, R3 is a C2 to C10 straight-chain or branched alkane comprising one to three oxygen atoms, and R2 is selected from the group consisting of: (i) H; (ii) halogen; (iii) C1 to C25 straight-chain, branched or cyclic alkane or alkene, optionally substituted with at least one member selected from the group consisting of Cl, Br, F, I, OH, NH2 and SH; (iv) C1 to C25 straight-chain, branched or cyclic alkane or alkene comprising one to three heteroatoms selected from the group consisting of O, N, Si and S, and optionally substituted with at least one member selected from the group consisting of Cl, Br, F, I, OH, NH2 and SH; (v) C6 to C20 unsubstituted aryl, or C3 to C25 unsubstituted heteroaryl having one to three heteroatoms independently selected from the group consisting of O, N, Si and S; and, (vi) C6 to C25 substituted aryl, or C3 to C25 substituted heteroaryl having one to three heteroatoms independently selected from the group consisting of O, N, Si and S; and wherein said substituted aryl or substituted heteroaryl has one to three substituents independently selected from the group consisting of: (1) C1 to C25 straight-chain, branched or cyclic alkane or alkene, optionally substituted with at least one member selected from the group consisting of Cl, Br, F I, OH, NH2 and SH, (2) OH, (3) NH2, and, (4) SH;and wherein X− is an anion.
