Porphyrin Pincer Complexes: Peripherally Cyclometalated Porphyrins and Their Catalytic Activities Controlled by Central Metals

摘要

We have achieved the synthesis of heterobimetallic porphyrin pincer complexes. Highly distorted structures of them have been revealed by X-ray analyses. These complexes exhibit markedly different catalytic activity in the typical Heck reaction depending on the central metals. Highly tunable nature of porphyrins by central metals and peripheral substituents should allow further creation of effective complexes for various transition-metal-catalyzed reactions.
