Aims: To achieve catalytic performance for the oxidation of alcohols using Ruthenium(III) metal complexes as a catalyst.

Background: Chitosan is a potential candidate, which enables the synthesis of transition metal complexes from its corresponding bidentate ligands.

Objective: The chemical modification was performed on a chitosan molecule with suitable aldehydes.

Methods: The oxidation of alcohols was performed using ruthenium metal complexes as a catalyst with pyridinium chlorochromate (PCC) as an oxidant and dichloromethane as a solvent. To a solution of alcohol (2 mmol) and dichloromethane (25 mmol), pyridinium chlorochromate (3 mmol), and ruthenium(III) complexes (0.01 mmol) were added. The solution was stirred for 12 h at room temperature. At the required time, the aldehyde/ketone was extracted with n-hexane. The nhexane was then analyzed by GC.

Results: The ruthenium(III) complexes derived from modified chitosan Schiff bidentate ligands have resulted in good catalytic performance for the oxidation of alcohols under optimized conditions.

Conclusion: The enhanced catalytic activities of ruthenium(III) complexes were due to the presence of electron-donating groups in the Schiff base ligand.

Keywords: Chitosan, NO donor ligands, ruthenium(III) complex, catalytic activity, schiff base, biopolymer.
