The synthesis and versatile reducing power of low-valent uranium complexes. Issue 43 (12th October 2020) - Boreen, Michael A.
Abstract : This synthesis and diverse reactivity of uranium(iii ) and uranium(ii ) complexes is discussed. Abstract : This Perspective provides a detailed overview of the chemistry of low-valent (di- and trivalent) uranium. The reactivity of uranium(ii ) and uranium(iii ) complexes is discussed both to illustrate the general types of reactions that might be expected and to highlight the many unusual modes of reactivity observed with this element. A particular emphasis is given to redox reactions with uranium(iii ) species, including reduction of small molecules, multi-electron reductions involving redox-active ligands, and formation of uranium–ligand multiple bonds. In addition, redox-neutral adduct formation with uranium(iii ) complexes as well as the current state of the young field of uranium(ii ) redox chemistry are also covered. Synthetic protocols to prepare a wide range of low-valent compounds are presented.
