Abstract Treatment of [Ir(PPh3)3Cl] with the 2-(1H-pyrrol-2-yl)pyridine (Hpp) ligand under refluxing toluene affords the iridium(III) hydride complex [Ir(H)Cl(pp)(PPh3)2] (1), whereas in the simultaneous presence of KOtBu the reaction gives iridium(III)… Click to show full abstract
Abstract Treatment of [Ir(PPh3)3Cl] with the 2-(1H-pyrrol-2-yl)pyridine (Hpp) ligand under refluxing toluene affords the iridium(III) hydride complex [Ir(H)Cl(pp)(PPh3)2] (1), whereas in the simultaneous presence of KOtBu the reaction gives iridium(III) hydride isomers, namely ortho-metallated triphenylphosphine cis-(P,P)-[Ir(H)(pp)(PPh3){K2C,P-PPh2(C6H4)}] (2) and trans-(P,P)-[Ir(H)(pp)(PPh3){K2C,P-PPh2(C6H4)}] (3). Complexes 1–3 are fully characterized by 1H NMR, 31P NMR, IR and UV–vis spectroscopy, together with single crystal X-ray diffraction analysis.
