Seven organic salts of 1-butyl-3-methylimidazolium with anions Br−, BF4 −, NO3 −, SO4 2−, HSO4 −, SCN−, PO 3−4 were prepared. Structure of these compounds is elucidated and purity is confirmed. The products are characterized by melting point, thinlayerchromatography, data of elemental analysis, cromatomass-, NMR and IR spectroscopy. All these compounds are ionic liquids, five are low temperature
A process for the preparation of the tertiary arylamine compound, comprising reacting and arylhalide, such as am arylbromide, and an arylamine in an ionic liquid in the presence of a catalyst.
