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 ...

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 ...

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

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

Andrzej Sienkiewicz, Rosario Scopelliti, Marinella Mazzanti

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 ...
