The Recent Developments of Photocatalytic Oxidation

The development of green and sustainable methods for "effective" synthesis of fine chemicals is an important goal for synthetic organic chemists. Oxidative reactions are an important process in Nature and constitute one of the most fundamental chemical transformations in organic synthesis. This chapter highlights the recent advances of visible-light-mediated aerobic oxidation and oxygenation reactions. The amine motif is a kind of good electron donor due to the nitrogen atom possessing lone pair electron, and they are the most common reductive quenchers for the photoredox catalysis, particularly tertiary amines. Visible-light-induced photocatalytic oxidation reactions of amines using oxygen as an oxidant have attracted significant interest from organic chemists. The photocatalytically generated imine intermediates have been applied into a series of nucleophilic addition and cycloaddition reactions. Transition metal-catalyzed C–H oxidative functionalization has proven to be a powerful tool for the construction of complex organic molecules.
