Abstract

There has been a growing interest in organometallic chemistry to utilize late Earth-abundant metals towards challenging molecular functionalization of abundant feedstocks to value-added products. There is precedent of utilizing cooperativity to try and address some of the shortcomings of traditional mononuclear complexes by integrating metal-metal and or metal-ligand cooperativity to facilitate multi-electron transformations. The utility of a redox-noninnocent scaffold allows for the metal centers to be stable over a range of oxidation states, using the ligand to store electrons. Despite recent progress, complexes harnessing cooperative states towards challenging transformations is still an emerging field. Our group has synthesized a multinucleating ligand able to house Ni centers in close proximity. These complexes demonstrate varying degrees of redox-noninnocence in the ligand scaffold through pyridyl-imine and bridged N-atom sites. Synthesis, characterization, and electronic structures of isolated Ni complexes will be discussed.
