Synthesis and characterization of transition metal complexes of methoxy and methyl substituted aminoaryl derivatives

Abstract

This research work entails the synthesis of transition metal complexes with methyl and methoxy aminoaryl derivatives. All the ligands were synthesized from readily available benzisothiazole. Various solvent systems, under different sets of reaction conditions were tried to develop a method for complex formation. Methanol was proved to be best solvent for complexation. The newly develop methodology was then applied to the synthesis of transition metal complexes which were identified by spectroscopic techniques. The structural assignments, of the ligands and the complexes were carried out by spectroscopic studies. Conclusively, higher activation energy was found to be involved in the synthesis of ligand molecule whereas the complexation appears to be a direct function of reaction time.
