The dianion of [2.2.2]paracyclophene; a 20 π-perimeter species?

1986

Abstract A new synthesis of [2.2.2]paracyclophene (1) is presented on reduction,(1) forms a stable dianion which is neither diatropic. nor paratropic. The apparent high symmetry of the dianion and the observed NMR chemical shifts are best explained by a rapid interconversion of a series of C 2-conformers.

Doubly charged ions of bridged [4n] annulenes. An evaluation of diatropic ring current effects.

1985

Abstract [4n]Annulenes are transformed into doubly charged ions (dianion, dication) and characterized NMR spectroscopically. The diatropic character of the ionic (4n+2)π-systems is studied as a function of the number of π-electrons.
