Evidence for ligand- and solvent-induced disproportionation of uranium(IV)

Autor: Jingzhen Du, Iskander Douair, Erli Lu, John A. Seed, Floriana Tuna, Ashley J. Wooles, Laurent Maron, Stephen T. Liddle

Publikováno v: Nature Communications, Vol 12, Iss 1, Pp 1-12 (2021)

Disproportion of uranium(IV) is rare, as it is usually the stable product of uranium(III) or (V) disproportionation. Here, the authors report uranium(IV) disproportionation to uranium(III) and (V) revealing ligand and solvent control over a key therm

Terminal uranium(V)-nitride hydrogenations involving direct addition or Frustrated Lewis Pair mechanisms

Autor: Lucile Chatelain, Elisa Louyriac, Iskander Douair, Erli Lu, Floriana Tuna, Ashley J. Wooles, Benedict M. Gardner, Laurent Maron, Stephen T. Liddle

Publikováno v: Nature Communications, Vol 11, Iss 1, Pp 1-12 (2020)

Despite their importance as mechanistic models for Haber Bosch ammonia synthesis from N2 and H2, high oxidation state terminal metal-nitrides are notoriously unreactive towards H2. Here, the authors report hydrogenolysis of a uranium(V)-nitride, whic

Emergence of the structure-directing role of f-orbital overlap-driven covalency

Autor: Erli Lu, Saira Sajjad, Victoria E. J. Berryman, Ashley J. Wooles, Nikolas Kaltsoyannis, Stephen T. Liddle

Publikováno v: Nature Communications, Vol 10, Iss 1, Pp 1-10 (2019)

In actinide chemistry, a longstanding bonding model describes metal-ligand binding using 6d-orbitals, with the 5f-orbitals remaining non-bonding. Here the authors explore the inverse-trans-influence — a case where the model breaks down — finding

Evidence for single metal two electron oxidative addition and reductive elimination at uranium

Autor: Benedict M. Gardner, Christos E. Kefalidis, Erli Lu, Dipti Patel, Eric J. L. McInnes, Floriana Tuna, Ashley J. Wooles, Laurent Maron, Stephen T. Liddle

Publikováno v: Nature Communications, Vol 8, Iss 1, Pp 1-10 (2017)

The reactivity of f-block complexes is primarily defined by single-electron oxidations and σ-bond metathesis. Here, Liddle and co-workers provide evidence that a uranium complex can undergo reversible oxidative addition and reductive elimination, de

The inverse-trans-influence in tetravalent lanthanide and actinide bis(carbene) complexes

Autor: Matthew Gregson, Erli Lu, David P. Mills, Floriana Tuna, Eric J. L. McInnes, Christoph Hennig, Andreas C. Scheinost, Jonathan McMaster, William Lewis, Alexander J. Blake, Andrew Kerridge, Stephen T. Liddle

Publikováno v: Nature Communications, Vol 8, Iss 1, Pp 1-11 (2017)

The inverse-trans-influence has been shown to operate in high oxidation state actinide complexes. Here, the authors report tetravalent cerium, uranium and thorium bis(carbene) complexes with trans C=M=C cores where experimental and theoretical data a

Correction: Author Correction: The inverse-trans-influence in tetravalent lanthanide and actinide bis(carbene) complexes

Publikováno v: Nature Communications, Vol 9, Iss 1, Pp 1-1 (2018)

Nature Communications 8: Article number: 14137 (2017); Published: 3 February 2017; Updated: 5 February 2018 The original version of this Article contained a typographical error in Fig. 2, where reagent H2C(Ph2PNSiMe3)2 was incorrectly given as H2C(PN

Publikováno v: Davison, N, Quirk, J, Tuna, F, Collison, D, Michaels, H, Morritt, G, Waddell, P, Gould, J, Freitag, M, Dawson, J 2022, ' A room-temperature-stable electride and its reactivity: Reductive benzene/pyridine couplings and solvent-free Birch reductions ', Chem, vol. 9 . https://doi.org/10.1016/j.chempr.2022.11.006

In this work, we report the synthesis of a room-temperature-stable electride (RoSE) reagent, namely K+(LiHMDS)e− (1) (HMDS: 1,1,1,3,3,3-hexamethyldisilazide), from accessible starting materials (potassium metal and LiHMDS) via mechanochemical ball
