Rhodium(Cp*) and iridium(Cp*) complexes with bidentate ligands and a coordinated oxygen atom transfer reagent as the final ligand in the d6 coordination sphere are described (Cp* = η5-pentamethylcyclopentadienyl). A Rh(Cp*) cation with a pyridyl-benzamide bidentate ligand resistant to insertion and a coordinated oxygen atom transfer reagent, 2-tert-butylsulfonyliodosylbenzene (sPhIO), was isolated

water oxidationcatalysts with bidentate ligands that are susceptible to oxidation. Monitoring the [Ir(Cp*)(phpy)(NCAr(F))](+) oxidation reaction by low-temperature NMR techniques revealed that the reaction involved two separate OAT events. An intermediate was detected, synthesized independently with trapping ligands, and characterized. The first oxidation step involves direct attack of the sPhIO oxidant
