Stabilized Gallylene in a Pincer-Type Ligand: Synthesis, Structure, and Reactivity of PGaIP-Ir Complexes
Iridium complexes having a pincer-type gallylene ligand were successfully synthesized utilizing bis(phosphino)terpyridine as an efficient scaffold for the Ir?GaI 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 PGaIP?Ir complexes.
