Ruthenium (II) and Iridium (III) Complexes of N-Heterocyclic Carbene and Pyridinol Derived Bidentate Chelates: Synthesis, Characterization, and Reactivity.

ABSTRACT: We report the synthesis and characterization of new ruthenium(II) and iridium(III) complexes of a new bidentate chelate, NHC^R'-py^OR (OR = OMe, OtBu, OH and R' = Me, Et). Synthesis and characterization studies were done on the following compounds: four ligand precursors (1-4); two silver complexes of these NHC^R'-py^OR ligands (5-7); six ruthenium complexes of the type [η⁶-(p-cymene)Ru(NHC^R'-py^OR)Cl]X with R' = Me, Et and R = Me, tBu, H and X = OTf^-, PF₆^- and PO₂F₂^- (8-13); and two iridium complexes, [Cp*Ir(NHC^Me-py^OtBu)Cl]PF₆ (14) and [Cp*Ir(NHC^Me-py^OH)Cl]PO₂F₂ (15).
