Abstract

Disclosed are a pincer-type ligand having a structurally rigid acridane structure and a metal complex consisting of the pincer-type ligand and a metal bound to each other, and exhibiting high reactivity and stability during a variety of bonding activation reactions. T-shaped complexes can be prepared fromPNP(4,5-bis(diisopropylphosphino)-2,7,9,9-tetramethyl-9H-acridin-10-ide), which is a pincer-type PNP ligand having an acridane structure, and metal complexes, which can be structurally rigid and thus exhibit excellent reactivity and stability based on minimized structural change thereof, can be prepared by introducing an acridane structure into the backbone thereof. The PNP ligand is structurally stable and has novel chemical properties, as compared to conventional similar ligands, and thus can be utilized in a wide range of catalytic reactions and material chemistry.
