“…Even tertiary diamines react sufficient with the tosylate of the primary hydroxyl group of cellulose and also asymmetric diamines can be applied for synthesis. The terminal tertiary amino moiety of the obtained derivative could be further converted in a ring-opening reaction to yield sulfobetainic polyampholytes based on cellulose (Pfeifer et al 2022). For cellulose, a regioselective functionalization at the primary hydroxyl group at C6 is achievable up to a DS of 0.8.…”

This review article is dedicated to special polysaccharide esters – the polysaccharide toluenesulfonic acid esters (tosylates) and polysaccharide carbonate esters. After describing the specifics of the synthesis, particular emphasis is placed on the use of polysaccharide tosylates and polysaccharide phenyl carbonates for subsequent modification by nucleophilic substitution (SN) reactions. For this purpose, the advantages and limitations of the respective derivatives are discussed with regard to their application in chemical modification with nucleophiles containing functional groups. A few functional polysaccharide derivatives and their properties are presented. Finally, reactive derivatives for click chemistry approaches are featured. These can be prepared starting from the reactive intermediate of either polysaccharide tosylate or polysaccharide phenyl carbonate.
