Enantiospecific Synthesis of Planar Chiral Rhodium and Iridium Cyclopentadienyl Complexes: Enabling Streamlined and Computer-Guided Access to Highly Selective Catalysts for Asymmetric C-H Functionalizations

Rosario Scopelliti, Nicolai Cramer, Farzaneh Fadaei Tirani, Matthew Wodrich, Rubén Laplaza Solanas, Anne-Clémence Corminboeuf, Aragorn Nathan Laverny

Chiral cyclopentadienyl (CpX) metal complexes are frequently used in asymmetric catalysis by virtue of their high reactivity and selectivity. Planar-chiral-only rhodium and iridium cyclopentadienyl complexes are particularly promising due to unrestricted c ...

Multielectron Redox Chemistry of Ytterbium Complexes Reaching the +1 and Zero Formal Oxidation States

Rosario Scopelliti, Marinella Mazzanti, Andrzej Sienkiewicz

Lanthanide redox reactivity remains limited to one-electron transfer reactions due to their inability to access a broad range of oxidation states. Here, we show that multielectron reductive chemistry is achieved for ytterbium by using the tripodal tris(sil ...

Electron Glass Phase with Resilient Zhang-Rice Singlets in LiCu3O3

Rosario Scopelliti, László Forró, Henrik Moodysson Rønnow, Arnaud Magrez, Krunoslav Prsa, Simon Karl Moser, Paul Gregory Freeman, Jens Christian Johannsen, Gianmarco Gatti, Edoardo Martino

LiCu3O3 is an antiferromagnetic mixed valence cuprate where trilayers of edge -sharing Cu(II)O (3d9) are sandwiched in between planes of Cu(I) (3d10) ions, with Li stochastically substituting Cu(II). Angle resolved photoemission spectroscopy (ARPES) and de ...

Siloxide tripodal ligands as a scaffold for stabilizing lanthanides in the +4 oxidation state

Rosario Scopelliti, Marinella Mazzanti, Ivica Zivkovic, Fang-Che Hsueh

Synthetic strategies to isolate molecular complexes of lanthanides, other than cerium, in the +4 oxidation state remain elusive, with only four complexes of Tb(iv) isolated so far. Herein, we present a new approach for the stabilization of Tb(iv) using a s ...

A trinuclear metallasilsesquioxane of uranium(III)

Rosario Scopelliti, Marinella Mazzanti, Farzaneh Fadaei Tirani, Ivica Zivkovic, Nadir Jori

The silsesquioxane ligand (Bu-i)(7)Si7O9(OH)(3) ((POSSH3)-P-iBu) is revealed as an attractive system for the assembly of robust polynuclear complexes of uranium(III) and allowed the isolation of the first example of a trinuclear U(III) complex ([U-3((POSS) ...

Molecular imine cages with π-basic Au3(pyrazolate) faces

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

One tetrahedral and two trigonal prismatic cages with π-basic Au3(pyrazolate)3 faces were obtained by connection of pre-formed gold complexes via dynamic covalent imine chemistry. The parallel arrangement of the Au3(pyrazolate)3 complexes in the prismatic ...

Synthesis, structure and redox properties of single-atom bridged diuranium complexes supported by aryloxides

Rosario Scopelliti, Marinella Mazzanti, Ivica Zivkovic, Luciano Barluzzi, Fang-Che Hsueh

Single-atom (group 15 and group 16 anions) bridged dimetallic complexes of low oxidation state uranium provide a convenient route to implement multielectron transfer and promote magnetic communication in uranium chemistry, but remain extremely rare. Here w ...

MOF-Based Solid-State Proton Conductors Obtained by Intertwining Protic Ionic Liquid Polymers with MIL-101

Paul Joseph Dyson, Rosario Scopelliti, Zhaofu Fei, Farzaneh Fadaei Tirani

Solid-state proton conductors based on the use of metal-organic framework (MOF) materials as proton exchange membranes are being investigated as alternatives to the current state of the art. This study reports a new family of proton conductors based on MIL ...

Isolation and redox reactivity of cerium complexes in four redox states

Rosario Scopelliti, Marinella Mazzanti, Andrzej Sienkiewicz, Fang-Che Hsueh

The chemistry of lanthanides is limited to one electron transfer reactions due to the difficulty of accessing multiple oxidation states. Here we report that a redox-active ligand combining three siloxides with an arene ring in a tripodal ligand can stabili ...
