The synthesis of the N-aryl-substituted PNP pro-ligands
H(PNnaphP) (N-di(2-diisopropylphosphine-4-methylphenyl)naphthylamine)
and H(PNtolP) (N-di(2-diisopropylphosphine-4-methylphenyl)-o-tolylamine) is reported. The corresponding iridium(III)
complexes, [(PNnaphP)Ir(H)Cl], [(o-methyl-PNtolP)Ir(H)Cl], [(o-aryl-PNtolP)Ir(H)Cl], [(PNnaphP)Ir(H)2], [(o-methyl-PNtolP)Ir(H)2], and
[(o-aryl-PNtolP)Ir(H)2], were also synthesized and structurally characterized, along with
reaction intermediates, demonstrating various ligand coordination
modes.
