ABSTRACT

The conformations of some 2,4,6-triarylpyridines, 2-aryl-4-phenyl-6-tert-butylpyridines, and the corresponding pyridinium cations in dioxane and acetonitrile solutions were determined from the Cotton-Mouton effect. These systems are nonplanar; the angles by which the aryl substituents at positions 2 and 6 of the heteroring are turned relative to the heteroring plane are close to those observed in biphenyl and its p-substituted derivatives; these angles depend on substituents in the rings and, in the case of cations, at the pyridinium nitrogen atom.
