摘要：

[2.2]Paracyclophanes possessing a substituent on the aromatic ring are dissymmetric compounds due to the restricted rotation of the benzene rings. For interconversion of enantiomers temperatures above 200-degrees-C are necessary. We have succeeded in resolving the enantiomers of some mono-substituted [2.2]paracyclophanes by enantioselective gas chromatography using 2,3-di-O-methylated beta-cyclodextrins with bulky O-(1,1,2-trimethylpropyl)-dimethylsilyl or O-tbutyledimethylsilyl substituents in the 6-position of the glucose units as chiral stationary phases.
