Abstract:
Caterpillar-motion like rotational isomerization of meso-aryl substituted [26]- and [28]hexaphyrins has been revealed for the first time. Two-electron oxidation and reduction induce reversible interconversion between N,N'-dimethyl [26]- and [28]hexaphyrins with a rotational isomerization, in which the N-methylated pyrroles move from the corner in the former to the centre in the latter.

Conjugated systems containing an even number of π-electron pairs undergo a conrotatory ring closure. For example, thermal electrocyclization of (2E,4E)-2,4-hexadiene, a conjugated diene containing two π-electron pairs, gives trans-3,4-dimethylcyclobutene.
