Pd-catalyzed annulation reaction of meso-hexynyl Zn(II) porphyrin with 4-amlno-3-lodopyrldlne efficiently provides meso-3-{5-azaindolyl)-substituted Zn(II) porphyrin as a major product, which assembles to form a slipped cofacial dimer by the complementary coordination of the pyridine molety to the Zn(II) center. 2-Iodoaniline and 2-Iodophenol also undergo this [3 + 2] annulation with the meso-hexynyl Zn(II) porphyrin to furnish meso-Indolyl- and benzofuranyl-substituted Zn(II) porphyrins, respectively.
