Abstract

A new porphyrin-like or “pentaplanar” macrocyclic ligand (9) has been synthesized by a McMurray coupling of 2,5-bis(5-formyl-4-propyl-2-pyrrolyl)thiophene, followed by air oxidation in chloroform. This highly stable macrocycle is aromatic, as evidenced by its UV-visible and 1H NMR spectra. The pathway to 9 as well as the synthesis of two asymmetric dipyrrolylthiophenes is also described.
