Abstract
S spremembami v kemični zgradbi naravnih polimerov lahko bistveno vplivamo na njihove lastnosti in možnosti uporabe. Preko sulfonatov je bil pripravljen cel spekter derivatov celuloze. Predvsem tozilati so odlični intermediati pri pripravi derivatov s posebnimi lastnostmi, saj je tozilatna skupina dobro izstopajoča in jo je mogoče zamenjati s številnimi nukleofilnimi reagenti, po drugi strani pa lahko služi tudi kot zaščitna skupina pri nadaljnji funkcionalizaciji preostalih hidroksilnih skupin.

Title:Sulfonic esters of cellulose
Abstract:
Altering the molecular structure of natural polymers enables development of new materials with special properties. Cellulose sulfonates, especially tosylates, have been used as intermediates for further functionalization of cellulose. Tosylate groups can be easily replaced by various nucleophiles to yield derivatives that cannot be prepared directly. On the other hand, tosylate groups may serve as protecting groups in subsequent modifications of the remaining hydroxyl groups.

Keywords:derivatives, sulfonates, tosylation, nucleophilic displacement reactions, protection group
