Organometallic f-block complexes with multiple electron reductive activation reactivity
Lundi 29 août 2016 14:00
- Duree : 1 heure
Lieu : ILL 4, Seminar Room (no 163), 71 avenue des Martyrs - Grenoble
Orateur : Polly ARNOLD (University of Edinburgh - U.K.)
The activation of small, traditionally inert molecules by metal complexes contributes to our fundamental understanding of metal-ligand bonding and can open up new areas of catalysis. We will present new uranium complexes with simple, bulky ligands than enable the binding and reductive activation of small molecules such as N2, and can promote C-O cleavage and C-C and C-B bond formation in carbon oxides and aromatic hydrocarbons. We will discuss new results arising from using larger, constraining ligands to preorganise and control these multi-electron reactions.
Arguably more importantly, the study of interactions of f-block cations with softer ligands provides important contributions to the understanding of covalency in f-element ligand bonding that is needed for nuclear waste handling. Time allowing, the electronic structure and magnetic behaviours of sets of new electron-rich, organometallic samarium, uranium and neptunium complexes will be compared.
