The homogeneous preparation of a cellulose p-toluenesulfonate (tosylate) in N,N-dimethylaceta-mid+lithium chloride (DMAc-LiCl) is hampered by solvolysis of the p-toluenesulfonyl chloride (tosyl chloride). This Vilsmeier-Haack type reaction results in competitive formation of cellulosep-toluenesulfon
