Synthesis of Ferrous Complexes 2,2-Bipyridine-5,5-Dicarboxylic Acid and Studied for its Antioxidant Properties

In this study, a new multidentate ligand based on the 2,2’-bipyridine derivatives incorporating diamide functional group were synthesized and their corresponding transition complexe with irone (II) were prepared. The lihgand were synthesized by oxidizing of the precursor compound of 5,5'- dimethyl-2,2'- bipyridine to the acid derivatives which was subsequently converted into the acidchloride derivatives with thonylchloride, then following treatment with the amines, pyridine 2 carboxmaide afforded the diamide-functionalised ligand. The structure of the ligand and the transition complex was confirmed by elemental analysis, NMR, FTIR, UV-Vis, and mass techniques.
