Cooperative or Oxidative Hydrogen Addition to 2-Hydroxypyridonate Iridium Complexes: Dependence on Oxidation State

Iridium(III)–pyridone complexes are commonly found to react in a cooperative and redox-neutral manner with dihydrogen and alcohols. In this work, the reactivity preferences of IrI–pyridone complexes were investigated under a variety of conditions. We have found that, in contrast to IrIII–pyridones, IrI–pyridone complexes display a strong preference to react non-cooperatively. With a new chelating 2-hydroxy-8-diphenylphosphinoquinoline ligand that does not dissociate after hydrogen addition, oxidative addition is still preferred. In the preparation of mono- and bidentate neutral and anionic pyridone ligands, Vaska's complex was used as a point of reference. We expect these findings to have implications for catalyst development in the field of metal–ligand cooperation.

Mechanism of the Reaction of Hydrogen and Phenylacetylene with IrH(CO)(PPh3)3. Kinetic Evidence for the Co-ordinatively Unsaturated IrH(CO)(PPh3) Species in Solution as Reactive Intermediates and for the Reaction of Hydrogen with the Co-ordinatively Saturated IrH(CO)(PPh3)3 Species

A kinetic study of the reaction between IrH(CO)(PPh3)3 and H2 or PhCCH provided evidence for the existence of the co-ordinatively unsaturated intermediate IrH(CO)(PPh3) in solution, as well as a direct attack of hydrogen on the co-ordinatively saturated IrH(CO)(PPh3)3.

New perspectives in hydroformylation: A para-hydrogen study

NMR studies on the reaction of Ir(CO)(PPh3)2(η 3-C3H5) with para-H2 and CO enable the complete mapping of the hydroformylation mechanism for an iridium monohydride catalyst via the detection of species which include iridium acyl and alkyl dihydride intermediates.

Parahydrogen enhanced NMR studies on thermally and photochemically generated products from [IrH3(CO)(PPh3)2]

Parahydrogen induced polarisation is used to enable the rapid NMR characterisation of thermally and photochemically generated complexes of general formula [IrH3(CO)3-x(PPh3)x] (x = 1-3).
