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.
