A catalytic cycle for oxidation of tert-butyl methyl ether by a double C−H activation-group transfer process [PDF]
, 2008 A square-planar, iridium(I) carbene complex is shown to effect atom and group transfer from nitrous oxide and organic azides, releasing the corresponding formate or formimidate and an iridium(I)−dinitrogen adduct.

Iridium complexes bearing a PNP ligand, favoring facile C(sp^3)–H bond cleavage [PDF]
, 2011 Hydrogen iodide is lost upon reaction of PNP with IrI_3, where PNP = 2,6-bis-(di-t-butylphosphinomethyl)pyridine to give crystallographically characterized Ir(PNP)*(I)_2, which reacts with H_2 to give Ir(PNP)(H)(I)_2.
