Ligand-Supported Facile Conversion of Uranyl(VI) into Uranium(IV) in Organic and Aqueous Media

Marinella Mazzanti, Rizlan Bernier-Latmani, Farzaneh Fadaei Tirani, Radmila Faizova

Reduction of uranyl(VI) to U-V and to U-IV is important in uranium environmental migration and remediation processes. The anaerobic reduction of a uranyl U-VI complex supported by a picolinate ligand in both organic and aqueous media is presented. The [(UO ...

The first metallasilsesquioxane of a divalent lanthanide, Yb{Cy7Si7O11(OSiMe3)}(THF),1, was synthesized and structurally characterized. The Cy7Si7O11(OSiMe3)(2-)ligands in1bind two Yb(ii) ions in a bridging mode. The dinuclear complex effects the two- ...

ROYAL SOC CHEMISTRY2020

Oxide is an attractive linker for building polymetallic complexes that provide molecular models for metal oxide activity, but studies of these systems are limited to metals in high oxidation states. Herein, we synthesized and characterized the molecular an ...

Anhydrous Conditions Enable the Catalyst-Free Carboxylation of Aromatic Alkynes with CO2 under Mild Conditions

Paul Joseph Dyson, Marinella Mazzanti, Felix Daniel Bobbink, Davide Toniolo

The direct carboxylation of aromatic alkynes with CO2, a cheap and widely available C1 source, is the most attractive method for the synthesis of carboxylic acids. Here we show that direct carboxylation of terminal alkynes can be simply performed in near-q ...

Stabilization of the Oxidation State plus IV in Siloxide-Supported Terbium Compounds

Rosario Scopelliti, Marinella Mazzanti, Ivica Zivkovic

The synthesis of lanthanides other than cerium in the oxidation state +IV has remained a desirable but unmet target until recently, when two examples of Tb-IV with saturated coordination spheres were isolated. Here we report the third example of an isolate ...

Synthetic studies of bimetallic uranium nitride complexes with the N(SiMe3)(2) ligand have generated a new nitride complex of U(III), which is highly reactive toward C-H bonds and H-2. Treatment of the previously reported U(IV)/U(IV) nitride complex [Na(DM ...

Accessing the plus IV Oxidation State in Molecular Complexes of Praseodymium

Marinella Mazzanti, Farzaneh Fadaei Tirani, Ivica Zivkovic

Out of the 14 lanthanide (Ln) ions, molecular complexes of Ln(IV) were known only for cerium and more recently terbium. Here we demonstrate that the +IV oxidation state is also accessible for the large praseodymium (Pr) cation. The oxidation of the tetraki ...

The hexanuclear [Na12Fe6(tris-cyclo-salophen)(2)(THF)(14)], 1-THF, and the trinuclear [Na6Fe3(tris-cyclo-salophen)(py)(9)], 1-py, Fe(II) clusters can be easily assembled in one step from the ligand-based reduction of the [FeII(salophen)(THF)] complex. Thes ...

Carbon Dioxide Reduction by Multimetallic Uranium(IV) Complexes Supported by Redox-Active Schiff Base Ligands

Rosario Scopelliti, Marinella Mazzanti, Marta Falcone, Nadir Jori

The synthesis, structure, and reactivity with CO2 and CS2 of new U(IV) complexes with a redox-active Schiff base are reported. The reaction of UI3 with the heptadentate Schiff base ligand 2,2',2 ''-tris(salicylideneimino)-triethylamine (trensal) did not le ...

AMER CHEMICAL SOC2020

We here report the synthesis and characterization of a complete series of terminal hydrochalcogenido, U–EH, and chalcogenido uranium(IV) complexes, U≡E (with E = O, S, Se, Te), supported by the (Ad,MeArOH)3tacn (1,4,7-tris(3-(1-adamantyl)-5-methyl-2-hydrox ...
