Stabilized Gallylene in a Pincer‐Type Ligand: Synthesis, Structure, and Reactivity of PGaIP‐Ir Complexes

Abstract Iridium complexes having a pincer‐type gallylene ligand were successfully synthesized utilizing bis(phosphino)terpyridine as an efficient scaffold for the Ir−Ga I bond. The stabilization of the gallylene moiety by the pincer‐type structure enabled various reactions at Ir with keeping the gallylene ligand intact, leading to unique structures and reactivities of PGa I P−Ir complexes.
