Therefore, bulky alkoxy substituents such as isopropoxy and isobutoxy improve resolving power [23]. Phenylcarbamate derivatives having both an electron-donating methyl group and electron-withdrawing substituents (chloro or fluoro groups), on the phenyl moieties were found to exhibit high enantioseparation for many racemates.

The introduction of an electron-donating methyl group or an electron-withdrawing halogen at the 3and=or 4-position improved the resolution ability, but substituents at position 2 showed poor chiral resolution capacity.

1 Analytical Separations A single CSP cannot be used for the chiral resolution of all racemic compounds. Therefore, different CSPs were used for the chiral resolution of different racemates. To make this part easy and clear, Table 1 includes the names of 20 CSPs and their most frequent applications. However, some other interesting applications are possible. Upon screening about 510 racemic compounds described in the literature, we observed that 229 of them resolved completely and 86 partially on cellulose tris(3,5-dimethylphenylcarbamate), and the rest not at all.
