Stereochemisty. Part III. Conformation of eight-membered heterocyclic rings. Conformation of NN-diphenyl-3,7-diaza-1,5-dithiacyclo-octane in dioxan solution
Abstract
A general method for defining the geometry of non-rigid ring systems has been developed by a modification of literature methods. Using this method, the resultant moments of different conformers of NN-diphenyl-3,7-diaza-1,5-dithiacyclo-octane have been calculated. These compounds prefer a crown conformation in dioxan solution with a diequatorial disposition of the substituents on nitrogen.
