CS2 Reductive Coupling to Acetylenedithiolate by a Dinuclear Ytterbium(II) Complex

Rosario Scopelliti, Marinella Mazzanti, Julie Renée Michelle Andrez, Davide Toniolo

The activation of CS2 is of interest in a broad range of fields and more particularly in the context of creating new C‐C bonds. The reaction of the dinuclear ytterbium(II) complex [Yb2L4], 1, (L = (OtBu)3SiO‐) with carbon disulphide led to the isolation of ...

A versatile route to homo- and hetero-bimetallic 5f–5f and 3d–5f complexes supported by a redox active ligand framework

Marinella Mazzanti, Julie Renée Michelle Andrez, Davide Toniolo

The salt-elimination reaction of the complex [Na2U(bis-salophen)] with metal halides provides an entry to the synthesis of well-defined homobimetallic uranium–uranium and rare heterobimetallic uranium–cobalt and uranium–nickel complexes supported by a redo ...

Ligand and Metal Based Multielectron Redox Chemistry of Cobalt Supported by Tetradentate Schiff Bases

Rosario Scopelliti, Marinella Mazzanti, Julie Renée Michelle Andrez

We have investigated the influence of bound cations on the reduction of cobalt complexes of redox active ligands and explored the reactivity of reduced species with CO2. The one electron reduction of [CoII(Rsalophen)] with alkali metals (M = Li, Na, K) lea ...

Uranium(IV) Terminal Hydrosulfido and Sulfido Complexes: The Nature of the Uranium–Sulfur Bond

Marinella Mazzanti, Julie Renée Michelle Andrez

Herein, we report the synthesis and characterization of a series of terminal uranium(IV) hydrosulfido and sulfido complexes, supported by the hexadentate, tacn-based ligand framework (Ad,MeArO)3tacn3– (= trianion of 1,4,7-tris(3-adamantyl-5-methyl-2-hydrox ...

Synthesis and reactivity of a terminal uranium(IV) sulfide supported by siloxide ligands

Rosario Scopelliti, Marinella Mazzanti, Julie Renée Michelle Andrez

The reactions of the tetrasiloxide U(III) complexes [U(OSi(OtBu)3)4K] and [U(OSi(OtBu)3)4][K18c6] with 0.5 equiv. of triphenylphosphine sulfide led to reductive S-transfer reactions, affording the U(IV) sulfide complexes [SU(OSi(OtBu)3)4K2]2, 1, and [{SU(O ...

Synthesis of molecular complexes for small molecule activation

Julie Renée Michelle Andrez

The redox chemistry of f-elements is drawing the attention of inorganic chemists due to their unusual reaction pathways. Notably low-valent f-element complexes have been shown to be able to activate small molecules such as CO2 and N2 in mild conditions. Co ...

Lanthanide(II) Complexes Supported by N,O-Donor Tripodal Ligands: Synthesis, Structure, and Ligand-Dependent Redox Behavior

Rosario Scopelliti, Marinella Mazzanti, Julie Renée Michelle Andrez

The preparation and characterization of a series of complexes of the Yb and Eu cations in the oxidation state II and III with the tetradentate N,O-donor tripodal ligands (tris(2-pyridylmethyl)amine (TPA), BPA(-) (HBPA=bis(2-pyridylmethyl)(2-hydroxybenzyl)a ...

CS2 activation at uranium(III) siloxide ate complexes: the effect of a Lewis acidic site

Marinella Mazzanti, Julie Renée Michelle Andrez

Multimetallic cooperative binding of heteroallenes provides an attractive route to their activation, but the reduction of CS2 at heterobimetallic sites, associating an electron-rich metal with a main group Lewis acid has not been explored. Here we show tha ...
