An Efficient, Scalable Approach to a Novel Dinuclear Nickel Complex

Shawn Daniel Montag, Purdue University


Discovering new types of catalysts is of vital importance as we seek more efficient methodologies to further advance organic synthetic techniques and energy conservation processes. Since the 1960s, a lot of research in this area has been in the field of redox-active ligand development. Furthermore, research conducted to use metal-metal bonds in catalysis remains scarce, due to inherent instability of metal-metal bonds, leading to decomposition. New catalytic platforms that support coordinatively unsaturated metal-metal bonds would then be of value. Utilizing a binucleating, redox-active ligand would allow for stabilization of these metal-metal bonds, due to electronic motion through the redox-active framework of the ligand, rather than that of the metal centers. Herein, the synthesis of a binucleating redox-active ligand is discussed, as well as other potential frameworks that could potentially stabilize two metal centers. The redox-active ligand was then subjected to metalation conditions, allowing for the formation of a naphthyridine dialdimine complex with a Ni—Ni bond. Two different complexes with two metal centers are discussed, as well as their full characterization. Lastly, the redox-active complex was subjected to catalytic cyclotrimerization conditions developed by our lab to determine its synthetic use in methodology development.
