Abstract
|
The condensation of primary amines with carbonyl compounds yields Schiff bases [1]. The preparation of a new ligand was a perhaps the most important step in the development of metal complexes which exhibit unique properties and novel reactivity [2]. Schiff bases and their biologically active complexes have been often used as chelating ligands in the coordination chemistry of transition metals, radiopharmaceuticals for cancer targeting[3], agrochemicals[4], model systems for biological macromolecules[5], catalysts[6] and as dioxygen carrier[7]. The interest in the study of compounds containing sulfur and nitrogen donor atoms arises from their significant antifungal, antibacterial, anticancer and catalytic activities.
In this study, we reported the synthesis of some new Schiff base compounds from 2-amino-3,5-dibromobenzaldehyde with aliphatic amines. The compounds were characterized by 1H NMR and IR spectroscopy. Then, the interactions of Schiff base ligands with metal ions were studied.
