Synthesis of N-fused dithia and dibenzi homoporphyrins

Abstract

N-fused dithia and dibenzi homoporphyrins have been synthesized using [2+2] approach by condensing one equivalent of appropriate dithienyl/di p-phenylene ethene diol with one equivalent of N-confused dipyrromethane in CH2Cl2 under...

The Intracavity Extension of 28-Hetero-2,7-naphthiporphyrins in Reactions with Alkylamines

“…Similar reactivity of the pyrrole of the macrocycle was previously demonstrated for N-fused porphyrins and carba- and heteroporphyrinoids. 32 − 37 The tetrahydroazepine ring adopted a boatlike conformation enforcing the endo -position of a hydrogen atom at the tetrahedral C8. The C30–C31 distance of 1.344(5) Å indicated a double-bond character, consistent with the valence structure depicted in Scheme 1 .…”
