Abstract:
In this paper data are presented suggesting that for enantiomers of basic and neutral analytes, the concentrations of highly sulfated CDs typically used are above the optimum since lower concentrations result in unacceptable migration times. This situation arises because of the high binding affinities often obtained with sulphated CDs. In a system being over the optimum CD concentration increasing the temperature of the capillary offers a capability to improve selectivity and reduce migration times.

Selection Rules: Thermal Activation
Conjugated systems containing an even number of π-electron pairs undergo a conrotatory ring closure. For example, thermal electrocyclization of (2E,4E)-2,4-hexadiene, a conjugated diene containing two π-electron pairs, gives trans-3,4-dimethylcyclobutene.
