- ... Glucosides having the hydroxyl groups at C-2 and C-3 individually substituted were treated with N,N-diethylaziridinium chloride in the presence of concentrations of sodium hydroxide ranging from 0.1m to 6.0m. Substitution of the hydroxyl group at C-2 greatly enhances the reactivities of the hydroxyl groups at C-3 and C-4 in dilute base but has less effect in more-concentrated base. Substitution of ...

- ... Cotton cellulose yarn, either in the untreated state, or altered by swelling pretreatments involving mercerization or solvent-exchange, or both, reacts readily with solutions of thionyl chloride in N,N-dimethylformamide at room temperature. Subsequent hydrolysis produces cellulose formate as the major product; this derivative is presumably formed via reaction of the cellulose with the iminium salt ...
