The reaction of 2-cyanothiophene with ethylenediamine under the irradiation of ultrasound waves produces a new imidazole ligand (L). The reaction of this ligand with copper(I) iodide in THF led to the CuI(L)2 complex. The structures of the synthesized compounds were studied with the help of FT-IR, 1H NMR, and combustion analysis techniques. The crystal structure of the copper(I) complex was determined by the single crystal X-ray diffraction technique, which revealed that the coordination geometry is square pyramidal and crystal packing is stabilized with the help of strong and weak non-covalent interactions. To further investigate the intermolecular interactions, Hirshfeld surface analysis (HSA) was carried out. The DFT parameters calculated with the use of the B3LYP/Def2-TZVP level of theory showed that the calculated outputs comply with the experimental results.

Novel imidazoline derivatives were synthesized from the norbornene and dibenzobarrelene skeletons which were obtained by the Diels-Alder reactions of anthracene and cyclopentadiene with the different dienophiles, such as fumaronitrile and fumaric acid. Synthesis of the C-2 substituted imidazolines was performed with high yields from various dinitriles and diacyl dichlorides.

Pyridoxal N(4)-substituted thisemicarbazone hydrochloride ligands (L1-3) were synthesized and reacted with the ruthenium(II) starting complexes [RuHCl(CO)(EPh3)3] (EP or As). The resulting complexes [Ru(CO)(L1-3)(EPh3)2] (1-6) were characterized by elemental analyses and spectroscopic techniques. The molecular structure of complex 5 was identified by means of single crystal X-ray diffraction analysis. The catalytic activity of the new complexes was evaluated for the selective hydration of nitriles to primary amides and also the condensation of nitriles with ethylenediamine under solvent free conditions. The processes were operative with aromatic, heteroaromatic and aliphatic nitriles, and tolerated several substitutional groups. The studies on the effect of substitution over thiosemicarbazone, reaction time, temperature, solvent and catalyst loading were carried out in order to find the best catalyst in this series of complexes and favourable reaction conditions. A probable mechanism for both the catalytic reactions of nitrile has also been proposed. The catalyst was recovered and recycled in the hydration of nitriles for five times without any significant loss of its activity.
