Structures of the two new compounds Ⅲd and Ⅲe were identified by their almost quantitative conversion to the known diperchlorate Ⅲa, by the determination of melting points and mixed melting points with samples prepared by a different route (vide infra), by the analogy of their ultraviolet spectra (Fig.1) as well as that of the diiodide Ⅲb, and by halogen elemental analyses.In addition to the dichloride Ⅲe, the reaction with carbon tetrachloride also yielded some 1,3-diphenylimidazolinium chloride (Ⅳ, ca.15%) and hexachloroethane.
