Uranyl to Uranium(IV) Conversion through Manipulation of Axial and Equatorial Ligands
ABSTRACT: The controlled manipulation of the axial oxo and equatorial halide ligands in the uranyl dipyrrin com-plex, UO2Cl(L) allows the uranyl reduction potential to be shifted by 1.53 V into the range accessible to naturally oc-curring reductants that are present during uranium remedi-ation and storage processes. Abstraction of the equatorial halide ligand to form the uranyl cation causes a 780 mV positive shift in the UV/UIV reduction potential. Borane-functionalization of the axial oxo groups causes the spon-taneous homolysis of the equatorial U-Cl bond and a fur-ther 750 mV shift of this potential. The combined effect of chloride loss and borane coordination to the oxo groups allows reduction of UVI to UIV by H2 or other very mild re-ductants such as Cp*2Fe. The reduction with H2 is accom-panied by a B-C bond cleavage process in the oxo-coordinated borane.
