Hydrogen iodide is lost upon reaction of PNP with IrI3, where PNP = 2,6-bis(di-t-butylphosphinomethyl)pyridine to give crystallog. characterized iridacycle Ir(PNP)*(I)2, which reacts with H2 to give Ir(PNP)(H)(I)2. Ir(PNP)(Cl)3 is relatively inert towards the intramol. C-H activation of the tert-butyl’s of the PNP ligand. Ir(PNP)(Cl)3 was characterized by x-ray crystallog.
