Cages vs. Prisms: Controlling the Formation of Metallosupramolecular Architectures with Ligand Side-Chains

Kay Severin, Rosario Scopelliti, Farzaneh Fadaei Tirani, Giacomo Cecot, Andrea Luca Ramorini, Ophélie Marie Planes, Martin Tim Doll

Metallosupramolecular assemblies of the general formula M2nLn can adopt prismatic or cage‐like structures. The factors controlling the aggregation number n and the geometry of the final assembly are still not fully understood. Here, we describe the synthes ...

Tuning reactivity of nitride bridged uranium complexes with amide and siloxide ligands

Rosario Scopelliti, Marinella Mazzanti, Luciano Barluzzi

AMER CHEMICAL SOC2019

Tuning the structure, reactivity and magnetic communication of nitride-bridged uranium complexes with the ancillary ligands

Rosario Scopelliti, Marinella Mazzanti, Anne-Clémence Corminboeuf, Ivica Zivkovic, Alberto Fabrizio, Luciano Barluzzi

Molecular uranium nitride complexes were prepared to relate their small molecule reactivity to the nature of the U & xe001;N & xe001;U bonding imposed by the supporting ligand. The U4+-U4+ nitride complexes, [NBu4][{(((BuO)-Bu-t)(3)SiO)(3)U}(2)(mu-N)], [NB ...

Synthesis of Organic Super-Electron-Donors by Reaction of Nitrous Oxide with N-Heterocyclic Olefins

Andrzej Sienkiewicz, Kay Severin, Rosario Scopelliti, Basile Curchod, Léonard Yannick Maurice Eymann, Farzaneh Fadaei Tirani, Yizhu Liu, Ophélie Marie Planes, Paul Varava, Andrei Shved

The reaction of nitrous oxide (N2O) with N-heterocyclic olefins (NHOs) results in cleavage of the N–O bond and formation of azo-bridged NHO dimers. The latter represent very electron-rich compounds with a low ionization energy. Cyclic voltammetry studies s ...

Molecular Complex of Tb in the +4 Oxidation State

Rosario Scopelliti, Marinella Mazzanti, Ivica Zivkovic

Lanthanides (Ln) usually occur in the +3, or more recently the +2, oxidation states. The only example of an isolated molecular Ln(4+) so far remains Ce4+. Here we show that the +4 oxidation state is also accessible in a molecular compound of terbium as dem ...

Ethynylbenziodazolones (EBZ) as Electrophilic Alkynylation Reagents for the Highly Enantioselective Copper-Catalyzed Oxyalkynylation of Diazo Compounds

Rosario Scopelliti, Jérôme Waser, Lionel Schouwey, Farzaneh Fadaei Tirani, Durga Prasada Rao Hari, Verity Barber

Ethynylbenziodoxol(on)e (EBX) cyclic hypervalent iodine reagents are now established reagents for the alkynylation of radicals and nucleophiles, yet they present limited possibilities for further structure and reactivity modification. Herein, the first syn ...

CO2 and CO/H-2 Conversion to Methoxide by a Uranium(IV) Hydride

Rosario Scopelliti, Marinella Mazzanti, Marta Falcone

Here we show that a scaffold combining siloxide ligands and a bridging oxide allows the synthesis and characterization of the stable dinuclear uranium(IV) hydride complex [K-2{U(OSi((OBu)-Bu-t)(3))(3)(mu-O)(mu-H)(2)}], 2, which displays high reductive ...

Towards Light-Activated Ruthenium-Arene (RAPTA-Type) Prodrug Candidates

Rosario Scopelliti, Paul Joseph Dyson, Patrycja Nowak-Sliwinska, Anna Katherine Renfrew, Felix Daniel Bobbink

Cancer is currently one of the deadliest diseases worldwide. Based on the high incidence of this disease, the side effects associated with current chemotherapies and the appearance of drug resistance, considerable efforts have been directed towards the dev ...

Synthesis, characterization and cytotoxicity of arene-ruthenium(II) complexes with acylpyrazolones functionalized with aromatic groups in the acyl moiety

Rosario Scopelliti, Paul Joseph Dyson, Tina Riedel

A series of neutral ruthenium(II)-arene complexes, [(arene) Ru(Q(R))Cl] (arene = p-cymene or hexamethylbenzene), containing 4-acyl-5-pyrazolonate (Q(R)) ligands with aromatic substituents in the acyl moiety (a phenyl in Q(Ph) and a 1-naphthyl in Q(naph)) a ...

Synthesis and Characterization of a Water Stable Uranyl(V) Complex

Rosario Scopelliti, Anne-Sophie Chauvin, Marinella Mazzanti, Radmila Faizova

We have identified a polydentate aminocarboxylate ligand that stabilizes uranyl(V) in water. The mononuclear [UO2(dpaea)]X, (dpaeaH2 = Bis(pyridyl-6-methyl-2-carboxylate)-ethylamine; X = CoCp2*+ or X = K(2.2.2.cryptand) complexes have been isolated from an ...

Influence of Functionalized η6 -Arene Rings on Ruthenium(II) Curcuminoids Complexes

Rosario Scopelliti, Paul Joseph Dyson, Tina Riedel, Laure Debora Pittet, Agnese Petrini

A series of organometallic Ru(II) complexes containing functionalized η6‐arene ligands, together with curcumin and bisdemethoxycurcumin as O,O’‐chelating ligands and their RAPTA (ruthenium arene complexes bearing the 1,3,5‐triaza‐7‐phosphaadamantane ligand ...

The effect of iron binding on uranyl(V) stability

Rosario Scopelliti, Marinella Mazzanti, Radmila Faizova

Here we report the effect of UO2+⋯Fe2+ cation–cation interactions on the redox properties of uranyl(V) complexes and on their stability with respect to proton induced disproportionation. The tripodal heptadentate Schiff base trensal3− ligand allowed the sy ...
