Ecofriendly Fast Synthesis of Hydrophilic Poly(ethyleneglycol)-Ionic Liquid Matrices for Liquid-Phase Organic Synthesis

Résumé

New, hydrophilic poly(ethyleneglycol)-ionic liquids have beensynthesized and investigated, based on 1,3-disubstituted imidazolium cations and fluorinated anions (BF4 -, PF6 -,(CF3SO2)2N-, or NTf2 -). A series of typical solvent-free reactions have been safely realized using a focused microwave reactor for the preparation of imidazolium chloride precursors in yields ranging from 73 to 94% followed by quantitative anion metathesis exchanges. The poly(ethyleneglycol)-ionic liquid matrices were also characterized by NMR (1H, 13C), mass spectrometry (MS), and their dynamic viscosity was determined at 25 °C. These poly(ethyleneglycol)-ionic liquid phases (PEGILPs) as task-specific ionic liquids are promising tools for synthetic applications in liquid-phase combinatorial chemistry.
