Redox-Active NOx Ligands in Palladium-Mediated Processes

This Minireview highlights the redox and non-innocent behavior of NOx ligands (x=1, 2, or 3) in selected Pd-mediated processes, for example, alkene and aromatic oxidation processes. A focus is placed on mechanistic understanding and linking recent transformations, such as CH bond activation/functionalization and Wacker oxidation, with previous work on the functionalization of aromatics and alkenes by Pd-II salts.
