✦ Synopsis
4n]Annulenes are transformed into doubly charged ions (dianion, dication) and characterized NMR spectroscopically. The diatropic character of the ionic (4n+2)n_systems is studied as a function of the number of m-electrons. '40.3 '4. A rotation of the transdouble bond around the neighboring single bonds would interconvert the magnetic sites of H-7 and H-8.
