selectively at the neighboring unsubstituted meso position to afford meso,β‐dihalo or meso,β,β‐trihaloporphyrins. Such oligohaloporphyrins are useful platforms for constructing more‐elaborate porphyrin‐based extended π systems. For example, meso‐chloro‐β,β‐diiodoporphyrin participated in an efficient single‐step synthesis of a diphenylamine‐fused porphyrin. In addition, meso‐chloro‐β‐iodoporphyrin was transformed
