Cooperative Catalysis by Iridium Complexes with a Bipyridonate Ligand: Versatile Dehydrogenative Oxidation of Alcohols and Reversible Dehydrogenation–Hydrogenation between 2-Propanol and Acetone

Cooperative Catalysis by Iridium Complexes with a Bipyridonate Ligand: Versatile Dehydrogenative Oxidation of Alcohols and Reversible Dehydrogenation–Hydrogenation between 2-Propanol and Acetone:

Going into reverse: An efficient and versatile catalytic system for the dehydrogenative oxidation of alcohols under extremely mild conditions is developed using a Cp*Ir complex with bipyridonate ligand as catalyst (see scheme, Cp*=pentamethylcyclopentadienyl). Reversible and repetitive transformation between 2-propanol and acetone by catalytic dehydrogenation–hydrogenation is also achieved.

Observation of the FeCN and FeCO Vibrations in the Active Site of [NiFe] Hydrogenase by Nuclear Resonance Vibrational Spectroscopy

Nuclear inelastic scattering of ⁵⁷Fe labeled [NiFe] hydrogenase is shown to give information on different states of the enzyme. It was thus possible to detect and assign FeCO and FeCN bending and stretching vibrations of the active site outside the spectral range of the FeS cluster normal modes.

Synthesis, Structure, and Reactivity of a Nickel Dihydrogen Complex

Synthesis, Structure, and Reactivity of a Nickel Dihydrogen Complex:

Hydrogen activation by nickel: A tBuPCP pincer ligand facilitates formation of cationic Ni^II dihydrogen and terminal dinitrogen complexes. The compounds have been characterized by X-ray crystallography and NMR spectroscopy. Addition of base promotes heterolytic cleavage of H₂ to form the corresponding neutral hydride complex .

Hydrogenation of a Rhodium Peroxido Complex by Formate Derivatives: Mechanistic Studies and the Catalytic Formation of H2O2 from O2

Hydrogenation of a Rhodium Peroxido Complex by Formate Derivatives: Mechanistic Studies and the Catalytic Formation of H2O2 from O2:

Hydrogenation of dioxygen: The rhodium peroxido complex 1, which can be prepared from 2 and dioxygen, can be reduced with dihydrogen sources to yield hydrogen peroxide. In a catalytic experiment, hydrogen peroxide is produced from dioxygen and ammonium formate under ambient conditions in the presence of 1 (see scheme).
