From the acid‐catalyzed condensation of aryl aldehyde and pyrrole a new type of fused expanded porphyrins, N ‐fused pentaphyrins NFP 5 ‐Y (24 π, yellow) and NFP 5 ‐R (22 π, red) were obtained in total yields of 2–19 %. The two normal‐type porphyrins are quantitatively interchanged through a redox reaction (see scheme). DDQ=2,3‐dichloro‐5,6‐dicyano‐1,4‐benzoquinone.
