Synthese et caracterisation de derives iminiques comportant des unites heterocycliques

Abstract

This work has object to synthesis and characterization new iminic derivatives with aromatic heterocyclic units. These compounds are in fact Schiff bases of the hydrazone and azine symmetrical unsymmetrical Schiff bases obtained from 2-furldéhyde, 2-pyrrole carboxaldéhyde and 2-hydroxy naphthaldehyde, and then to demonstrate their chelating power with respect to a few divalent metals to prepare mono and binuclear materials. All the compounds prepared are characterized using IR and UV-vis spectroscopic techniques and subjected to an electrochemical study. In a second part, an attempt at evaluation of the biological properties is carried out on the for azines L3, L4,L5 and L6 and finally a computational study using the theory of DFT is made on the two new unsymmetrical azines L4 and L5 whose structures have were determined by the X-ray diffraction technique performed on single crystals. The results obtained seem relevant and prompt further investigation
