5,15‐Porphyrinquinone is a non‐aromatic and electron‐deficient porphyrinoid that acts as an important framework for the synthesis of porphyrinoid derivatives. Generally, meso‐functionalized A2‐porphyrinquinone is synthesized via the oxidation of A2‐porphyrin. Herein, we present the stereoselective synthesis of AB‐porphyrinquinone Pt(II) complexes using the corresponding dipyrrinato‐Pt complexes and bisformyldipyrrins. The reaction involves cyclization and oxidative aromatization induced by the Pt template, followed by oxidation using a mild MnO2 oxidant.
