Abstract

New, hydrophilic poly (ethyleneglycol)-ionic liquids have been synthesized 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 ...
