The discovery of new catalysts is central to the pursuit of more efficient and sustainable processes in organic synthesis. While mononuclear transition metal complexes have been widely utilized in reaction methodology, the scope of both stoichiometric and catalytic processes for complexes of higher nuclearity is comparatively limited. In principle, multinuclear complexes might engage in unprecedented modes of reactivity by binding substrates and engaging in redox processes that span multiple metal centers. New classes of catalysts that capitalize on these cooperativity effects have the potential to exhibit activity or selectivity profiles that complement existing mononuclear systems. This seminar will describe our recent investigations of dinuclear nickel catalysts bearing redox-active supporting ligands. Transformations of alpha olefin substrates, including hydrosilylation and cyclopropanation reactions, will be highlighted, emphasizing the unique catalytic properties of nickel–nickel bonds.
