Abstract

A conformational analysis has been performed on 1,2-dipyridiniumethane and 1,2-diisoquinoliniumethane, using data on the Cotton-Mouton effect in water and in methanol. It has been shown that, in comparison with the 1,2-dibenzyl derivatives, in aqueous media, an abnormally high excess of the gauche conformer over the trans conformer is observed, an effect that is attributed to the formation of hydrate bridges.
