Is the [9]Annulene Cation a Möbius Annulene?

Angewandte Chemie International Edition, 2009
Does it do the twist? High-level theoretical calculations show that the [9]annulene cation exists in two isomers: a twisted 4n electron Mobius aromatic compound, and a non-twisted boat-like Huckel conformation (see scheme). The latter form was detected by laser flash photolysis experiments; an example of a stable, charged, or uncharged parent Mobius ...

Annulenes. Part XII. The dianion of [12]annulene

J. Chem. Soc. B, 1971
[12]Annulene is very unstable and can be reduced by alkali metals at –80° to the corresponding dianion. An n.m.r. study of this species clearly indicates that (i) it has the same perimeter configuration as the parent [12]-21-annulene, (ii) it presents a diamagnetic ring current (14 π-electrons, τ 14·60 for the three inner protons), it is thermally much
