Synthesis of 1-[1H,1H,2H,2H-perfluooctyl]-3-[2-(oxiran-2-yl)ethyl]imidazolium 4-[(2-oxiran-2-yl)ethoxy]benzenesulfonate as a New Perfluorinated Ionic Monomer

Access to perfluorinated compounds represents a growing challenge in the academic and industrial fields achieve target with specific physico-chemical properties. Especially, insertion of chain within an ionic liquid can provide improvements not just terms hydrophobicity lipophobicity, but also viscosity, density as well thermal stability. In this research area, we have recently developed new access points several epoxy imidazolium salts combined fluorinated anions such bistriflimide (NTf2−), hexafluorophosphate (PF6−) or tetrafluoroborate (BF4−). Here, reported synthesis cation associated sulfonate anion functionalized partner. This sequence required four steps from imidazole (cationic part) three sodium 4-hydroxybenzenesulfonate (anionic part), respectively. was fully characterized by nuclear magnetic resonance 1H-NMR, 19F-NMR, 13C-NMR, DEPT, COSY, HSQC, HMBC IR spectroscopy. The two parts salt were confirmed high-resolution mass spectrometry (HRMS), thermogravimetric analysis (TGA) differential scanning calorimetry (DSC) determine properties compound.
