C−C Bond Cleavage and Carbonylation Enabled by an NNN-Pincer Uranium Scaffold via Metal-Arene Interaction

Rosario Scopelliti, Marinella Mazzanti

Raw data accompanying the paper. Metal-arene complexes have recently attracted an increasing interest in f-element chemistry, but the functionalization of arenes mediated by uranium-arene interactions is limited to a single example. Here, we report a new ...

The constitutional dynamic chemistry of Au3(pyrazolate)3 complexes

Rosario Scopelliti, Kay Severin, Farzaneh Fadaei Tirani, Noga Eren

Trinuclear Au3(Pz)3 complexes (Pz = pyrazolate) have been used extensively as components in molecular and polymeric nanostructures. However, the constitutional dynamic chemistry of Au3(Pz)3 complexes remains largely unexplored. We have investigated exchang ...

Ambiphilic Reactivity of Iridium Complexes with N-Heterocyclic Vinylidene Ligands

Rosario Scopelliti, Kay Severin, Farzaneh Fadaei Tirani, Tak Hin Wong, Paul Varava

Room-temperature stable diazoolefins provide access to a unique class of carbon-donor ligands: N-heterocyclic vinylidenes. Herein, we describe iridium complexes with terminal N-heterocyclic vinylidene ligands. Cationic complexes of type [Cp*IrClL]X (X = Sb ...

Dinitrogen Reduction and Functionalization by a Siloxide Supported Thulium-Potassium Complex for the Formation of Ammonia or Hydrazine Derivatives

Rosario Scopelliti, Marinella Mazzanti, Ivica Zivkovic

The dinitrogen (N2) chemistry of lanthanides remains less developed compared to the d-block metals and lanthanide-promoted N2 functionalization chemistry in well-defined lanthanide complexes remains elusive. Here we report the synthesis and characterizatio ...

Facile N-C bond cleavage and arene reduction by a transient uranium(ii) complex

Rosario Scopelliti, Marinella Mazzanti, Andrzej Sienkiewicz, Ivica Zivkovic

Complexes of uranium(ii) remain extremely rare and their reactivity is practically unexplored. Here we report that the reduction of the heteroleptic bis-aryloxide U(iii) complex [U(κ6-{(tBu2ArO)2Me2-cyclam})I], A, yields a rare and highly reactive U(ii) in ...

Catalytic and stoichiometric stepwise conversion of side-on bound dinitrogen to ammonia mediated by a uranium complex

Rosario Scopelliti, Marinella Mazzanti, Ivica Zivkovic, Lucile Sylvie Danielle Chatelain

The well-defined catalytic conversion of dinitrogen (N2) to ammonia (NH3) by molecular complexes is of fundamental interest and important for providing an atomic-level understanding of reactivity that can be related to industrial and biological nitrogen-fi ...

Azide as a photolabile ligand in gold(I) therapeutics

Paul Joseph Dyson, Rosario Scopelliti, Farzaneh Fadaei Tirani, Kedar Ashok Abhyankar

Gold-based compounds are gaining attention as potential alternatives to platinum-based chemotherapeutics due to their high antiproliferative activity and unique mechanisms of action. However, challenges remain in enhancing their selectivity and reducing si ...

Iron promoted end-on dinitrogen-bridging in heterobimetallic complexes of uranium and lanthanides

Rosario Scopelliti, Marinella Mazzanti, Nadir Jori

End-on binding of dinitrogen to low valent metal centres is common in transition metal chemistry but remains extremely rare in f-elements chemistry. In particular, heterobimetallic end-on N2 bridged complexes of lanthanides are unprecedented despite their ...

Decoupling Interlayer Spacing and Cation Dipole on Exciton Binding Energy in Layered Halide Perovskites

Nicolas Grandjean, Rosario Scopelliti, Kevin Sivula, Jun Ho Yum, Han-Hee Cho, Simon Nussbaum, Yeonju Kim

Layered halide perovskites (LHPs) are emerging semiconductor materials due to their superior environmental stability compared to that of traditional halide perovskites. While LHPs have tunable optoelectronic properties, quantum and dielectric confinement e ...

Two-Electron Redox Reactivity of Thorium Supported by Redox-Active Tripodal Frameworks

Rosario Scopelliti, Marinella Mazzanti, Damien Wen Chen, Fang-Che Hsueh

The high stability of the + IVoxidation state limits thorium redox reactivity. Here we report the synthesis and the redox reactivity of two Th(IV) complexes supported by the arene-tethered tris(siloxide) tripodal ligands [(KOSiR2Ar)3-arene)]. The two-elect ...
