Isolation of a uranium(iii) benzophenone ketyl radical that displays redox-active ligand behaviour?
Dalton Transactions Pub Date: 2014-07-24 DOI: 10.1039/C4DT01636J
Abstract
The first uranium(III) charge separated ketyl radical complex, Tp*2U(OC·Ph2), has been isolated and characterized by infrared, 1H 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.
