“…Many reports described the catalytic abilities of ILs including: Friedel-Crafts reactions, Beckmann rearrangement, esterification, carbonylation reactions, and benzylation of alcohols [7,8]. In addition, ILs have following applications: as reagents and scavengers, to synthesize energy storage materials, to desulfurize fuel, for energy production, for carbon capture, functional material, and in denitrogenating of fuel oils [9]. According to their applications, many kinds of ILs were synthesized till now: acidic ILS, functionalized ILs, covalently and non-covalently supported ILs, ILs transported into metal-organic frame-works (MOFs), superionic liquids, and magnetic ILs, which each of them have their unique properties [10].…”

Ionic liquids (ILs) are mostly composed of organic cations and organic/inorganic anions. One of the most important class of ILs are imidazolium ILs. The hydrophilicity and hydrophobicity of ILs are regularly influenced by length of alkyl side chain of cation. According to this effect, better hydrophilicity comes from a shorter alkyl side chain and on the contrary, better hydrophobicity comes from a lengthier alkyl side chain of cation. Typical ILs have exceptional properties. Most ILs are stable at about 300 o C in the liquid state at normal conditions. Due to the exceptional properties of ILs, they have been used in diverse industries including batteries and fuels. As solvents, ILs have been employed in many chemical fields. Solubilities of ILs with organic/inorganic species are completely satisfactory. Here, by N-methyl imidazole (Im), 1,3-dibromopropane, triethanolamine (TEA), and ZnBr2, new ionic liquid (TEA-Im-Zn) was synthesized and used as catalyst and solvent in the synthesis of functionalized 1-benzamino-1,4-dihydropyridine using aromatic aldehydes, malononitrile, triethylamine, arylamine and dialkyl acetylenedicarboxylate.
