Abstract:
The facile electrosynthesis of π-extended porphyrins is demonstrated for a series of Zn(II), In(III), Ir(III) and free-base meso-substituted derivatives containing the 4,7-dimethoxynaphthalen-1-yl substituent. Electrochemical data suggest that the overall process initially involves two stepwise one-electron oxidations, followed by an intramolecular oxidative aromatic coupling to give the electrooxidized π-extended porphyrin.

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.
Pericyclic Reactions: Introduction
Pericyclic reactions can be classified into three categories: electrocyclic reactions, cycloaddition reactions, and sigmatropic rearrangements. Electrocyclic reactions and sigmatropic...
