Synthesis and catalytic application of schiff base complex base on 2 aminopyridine ligand from oxidized cellulose

Cellulose is an attractive raw material that has lately become more interesting thanks to its degradability and renewability and the environmental awareness of our society. In this work, dialdehyde cellulose (DAC) is a derivative that is produced by selective cleavage of the C2-C3 bond in an anhydroglucose unit in the cellulose chain, utilizing sodium periodate (NaIO4) that works as a strong oxidant. The synthesis of novel Schiff base (cellulose-2,3-bis-[2- aminopyridine]) via condensation reactions of periodate oxidized extracted cellulose was reported. Manganese complex of it was used as heterogamous catalyst for oxidation of alcohols.
