Abstract

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

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

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

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 n-hexane was then analyzed by GC.

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.

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