Abstract

A mild, efficient and eco-friendly procedure for the synthesis of novel ionic liquids (ILs) with formula (C₄H₉)₄NX-nC₆H₁₁NO (X=C^-, Br^- and Ac^-, n=2-3) under microwave irradiation and solventless conditions has been investigated. The materials have been characterized by IR, ¹H NMR methods. The properties of this kind of ILs have been researched including the melting point, the viscosity, the solubility, the pH value and the conductivity. Further, these ILs have been exploited for the synthesis of Michael addition using nano-KF/Al₂O₃ as catalyze in short duration of time with quantitative yields, for the first time.
