TRIS(CHLORO-DISUBSTITUTED AND METHYL-DISUBSTITUTED PHENYLCARBAMATE)S OF CELLULOSE AS CHIRAL STATIONARY PHASES FOR CHROMATOGRAPHIC ENANTIOSEPARATION

Four types of tris(chloro- and methylphenylcarbamate)s of cellulose were prepared and their chiral recognition abilities were evaluated as chiral stationary phases (CSPs) for HPLC. It has been established that simultaneous introduction of both electron-donating and electron-withdrawing groups improved enantiomer resolving power of CSP in some cases compared with those possessing only electron-donating or electron-withdrawing substituents.
