Benzene- and pyridine-incorporated octaphyrins with different coordination modes toward two PdII centers

Abstract

The reactivity of expanded porphyrins is highly influenced by their scaffold architecture. Here, the authors construct two nonaromatic dumbbell-shaped benzene- and pyridine-incorporating octaphyrins via Suzuki-Miyaura cross-coupling; depending on the framework, different coordination modes are obtained upon metallation with Pd(II).
