Inverted N‐Confused Porphyrin Dimer

A covalently linked N-fused porphyrin dimer was synthesized by treatment of the monomer with Ag(OCOCF3). Subsequent reaction of this dimer with NaOMe led to a porphyrin dimer with two α,β-bound (“confused”) pyrrole rings (see scheme) which adopt the inverted conformation. The dimer exhibits aromaticity in spite of its highly distorted structure.
