The influence of substituents on the rotational energy barrier of a series of 2,2′-bis(trifluoromethyl)- and 2,2′-diisopropylbiphenyl derivatives with various substitution patterns was investigated by dynamic gas chromatography (DGC) with selecti

We synthesized numerous new monosubstituted dioxa[11]-paracyclophanes, which are planar-chiral atropisomers due to the hindered rotation of the bridge about the aromatic plane, and we were able to resolve the enantiomers of these compounds by enantio

A number of variously monosubstituted 1,n-diaza[n]paracyclophanes (n = 10–12), which show planar chirality and atropisomerism due to hindered rotation about single bonds, were synthesized via a classical route to analyze their stereodynamic propert

X-ray structural analysis of octakis(dimethylamino)porphyrazinato-metallo(II)·[60]fullerene complexes (M = Cu2+ and Ni2+) surprisingly revealed two totally different supramolecular structures, the first exhibiting a Ci symmetric sandwich complex of

We herein report on the synthesis of substituted carbocyclic [11]paracyclophanes, which are planar-chiral and atropisomeric. Their energy barrier to rotation was determined by dynamic enantioselective gas chromatography on selectively modified cyclod

The enantiomers of the polychlorinated polycyclic xenobiotics heptachlor, cis- and trans-chlordane, cis- and trans-heptachlorepoxide, oxychlordane, and bromocyclen have been resolved by gas chromatography with selectively substituted cyclodextrins. T

[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 °C are necessary. We have succeeded in resol

Enantioselective gas chromatography with modified cyclodextrins as stationary phases is successfully used to separate chiral allenic hydrocarbons - including kinetically labile 1,2-cyclooctadiene - and 1-halo-1,2-butadienes.
