This study aims to prepare charge transfer complexes derived from organochalcogenide of arylamide derivatives with different quinones. A new charge-transfer complexes have been developed through a direct reaction between (' antioxidant activity was evaluated through α,α-diphenyl-β-picrylhydrazyl at 10-0.312 mg/mL. The results showed that all comple...

... The data suggest that precursor complexes and free ligands exhibit significantly weaker scavenging effects compared to their Fe(II) complexes, primarily due to the organic ligand's chelation with Fe(II). While the radical scavenging mechanism of these complexes remains unclear, the experimental results provide valuable insights for the development of more potent antioxidants [26]. ...
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.
