Reaction of Molecular Oxygen with a Pd~(II)-Hydride To Produce a Pd -Hydroperoxide: Acid Catalysis and Implications for Pd-Catalyzed Aerobic Oxidation Reactions

摘要

Palladium-catalyzed reactions are among the most versatile methods for the selective aerobic oxidation of organic molecules.These reactions are generally thought to proceed by a two-stage "oxidase" pathway that consists of Pd~(II)-mediated oxidation of the organic substrate followed by dioxygen-coupled oxidation of the Pd~0 center.
