title: Isolation of a uranium(III) benzophenone ketyl radical that displays redox-active ligand behaviour.
abstract: The first uranium(III) charge separated ketyl radical complex, Tp*2U(OC·Ph2), has been isolated and characterized by infrared, (1)H NMR, and electronic absorption spectroscopies, along with X-ray crystallography. Tp*2U(OC·Ph2) is a potent two-electron reductant towards N3Mes (Mes = 2,4,6-trimethylphenyl) and (2,2,6,6-tetramethyl-piperidin-1-yl)oxyl (TEMPO), with reducing equivalents derived from the metal centre and the redox-active benzophenone.
