摘要：

Partial oxidation of cellulose with sodium periodate (or periodic acid) is one of the most versatile transformations since it provides access to various novel products and intermediates with valuable properties. Moreover, the reaction is a regioselective oxidation of the glycopyranose ring of cellulose, while the glycosidic linkages remain intact. The water insoluble product, 2,3-dialdehyde cellulose without glycopyranose ring,has found considerable interest, for obtaining carriers for enzymes, heparin-like anticoagulation activity, Schiff's base of cellulose, and for the design of advanced materials[1-3].
