NEW ROOM TEMPERATURE LIQUIDS: SYNTHESIS AND CHARACTERIZATION

Abstract

Room temperature ionic liquids (ILs) have been recognized as a new generation of solvents for “green chemistry” and represent remarkably promising classes of technologically useful and fundamentally interesting materials [1-6]. Most of them are quaternary imidazolium cations with inorganic counterions. Cation in these salts is appended to the organic group (usually saturated hydrocarbon fragments). However, some problems regarding the functionalization [2,7], coordination properties [4] of ILs still remain to be solved. It seems to us that functionalization of imidazoles by ethylcarbonitrile, allyl, 2,3-epoxypropyl fragments will lead to new properties of synthesized ILs. There are no literature data on use of 2-(1H-1-imidazolyl)ethylcarbonitrile 4 for synthesis of imidazolium salts with ILs properties.
