Abstract
trans-1,2-Bis([2.2]paracyclophanyl)ethene (1) exists as a pair of diastereomers whose conformations, and thus effective collision cross sections, are quite different. The two forms can be obtained by different transition metal-catalyzed reactions. To assign meso and racemic structures, a novel method is reported in which experimental gas-phase ion mobility data are compared with theoretical structures obtained from molecular mechanics calculations.Keywords
