Expanded porphyrins have received considerable attention due to their unique optical, electrochemical and coordination properties. Here, we report benzene- and pyridine-incorporated octaphyrins(1.1.0.0.1.1.0.0), which are synthesized through Suzuki-Miyaura coupling of α,α′-diboryltripyrrane with  m- dibromobenzene and 2,6-dibromopyridine, respectively, and subsequent oxidation with 2,3-dicyano-5,6-dichlorobenzoquinone. Both octaphyrins are nonaromatic and take on dumbbell structures. Upon treatment with Pd(OOCCH 3 ) 2 , the benzene-incorporated one gives a C i  symmetric NNNC coordinated bis-Pd II  complex but the pyridine incorporated one gives C i  and C s  symmetric NNNC coordinated bis-Pd II  complexes along with an NNNN coordinated bis-Pd II  complex bearing a transannular C–C bond between the pyrrole α-positions. In addition, these two pyridine-containing NNNC Pd II  complexes undergo trifluoroacetic acid-induced clean interconversion.
