In situ coupled oxidation cycle catalyzed by highly active and reusable Pt-catalysts: Dehydrogenative oxidation reactions in the presence of a catalytic amount of o-chloranil using molecular oxygen as the terminal oxidant

10.1039/c0cc02865g

The study presents an in situ coupled oxidation cycle that enables catalytic oxidation of substrates using catalytic amounts of o-chloranil and novel, reusable polymer-immobilized platinum nanocluster catalysts, with molecular oxygen serving as the terminal oxidant. The chemicals used in the study include o-chloranil, a quinone with high oxidation potential, and platinum nanocluster catalysts, which are immobilized on a polymer matrix. These catalysts were designed to overcome the challenges associated with the stoichiometric use of quinones in organic synthesis, such as difficulty in removing by-products and high costs. The purpose of these chemicals was to facilitate a more environmentally friendly and economically viable oxidation process, where molecular oxygen, being abundant and producing water as the only by-product, was utilized as the ideal oxidizer. The study demonstrated the effectiveness of this system in the oxidation of dihydropyridines to pyridines, among other reactions, and showed that the platinum catalysts could be reused multiple times without significant loss of activity.
