Controlling electronics for the formation of high valent uranium imido complexes
… 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 …
