Redox-Active Ligand Uranium Complexes For Approaches To Multi-Electron Chemistry, John J. Kiernicki
Redox-Active Ligand Uranium Complexes For Approaches To Multi-Electron Chemistry, John J. Kiernicki
Open Access Dissertations
While transition metal complexes are known to participate in multi-electron redox chemistry to facilitate important organometallic transformations, actinides, due to their low redox potentials, have a propensity to perform single electron chemistry. Because of its highly reducing nature, the ability to control the electronics of low-valent uranium is highly sought after as this may lead to unprecedented reactivity. Our lab has specifically been interested in mediating multi-electron transformations at uranium by employing redox-active ligands. Redox-active ligands can be used to facilitate multi-electron processes such as oxidative addition and reductive elimination at single metal centers. Using primarily 2,6-((Mes)N=CMe)2C5H3N) ( MesPDIMe) as …

Controlling Electronics For The Formation Of High Valent Uranium Imido Complexes, Nickolas H. Anderson
Open Access Dissertations
Known primarily for its single electron chemistry, controlling the electronics at uranium to facilitate multi-electron processes remains a fundamental challenge in the actinide sciences. Our group has implemented the use of redox-active ligands to assist in the stabilization of low-valent uranium analogues, capable of performing multi-electron chemistry at a single uranium center. Of particular interest to our group are high-valent imido complexes, which are ubiquitous in organometallic and coordination chemistry due to their unique bonding properties and their ability to mediate bond-forming reactions. Uranium imido complexes, in particular, are the subject of much research to determine the degree of f- …
