Four cellulose mixed 10-undecenoate/carbamate derivatives, simultaneously bearing 10-undecenoyl and variously substituted phenylaminocarbonyl groups, were chemically bonded on allylsilica gel. The study of the effect of these substitutions on the performance of the resulting chiral supports, and a c

✦ Synopsis
In order to generalize the recently described method for the insolubilization of polysaccharide derivatives to benzoates of cellulose, five mixed 10undecenoate/benzoates of this polysaccharide have been prepared and linked to allyl silica gel by means of a radical reaction. The chiral recognition ability of the resulting materials when used as high-performance liquid chromatographic chiral stationary phases was evaluated using heptane/2-propanol and heptane/chloroform mixtures as mobile phases.
