Abstract

Abstract 6, 11, 16, 21-Tetraaryl-3-aza-m-benziporphyrin, an analog of 5, 10, 15, 20- tetraarylporphyrin with one of the pyrrole units replaced by a pyridine ring pointing outwards, linked at β, β′ positions, was formed by condensation of 3, 5-bis [phenyl (2-pyrrolyl) methyl] pyridine, pyrrole and p-tolualdehyde catalyzed by TFA. The [3+ 1] approach, which involved a condensation of 3, 5-bis [phenyl (2-pyrrolyl) methyl] pyridine with 2, 5-bis [hydroxy (p- ...
