Metal-catalyzed C–N cross-coupling generally forms C−N bonds by reductive elimination from metal complexes bearing covalent C- and N-ligands. We have identified a Cu-mediated that uses dative N-ligand in the bond-forming event, which, contrast to conventional methods, generates reactive cationic products. Mechanistic studies suggest process operates via transmetalation of an aryl organoboron Cu...

The mechanistic details associated with the generation and reaction of [CuO]+ species from CuI-[alpha]-ketocarboxylate complexes, especially with respect to modifications of the ligand supporting the copper center, were investigated (see scheme). Theoretical models were used to characterize the electronic structures of different [CuO]+ species and their reactivity in C—H activation and O-atom t...
