I am interested in the chemistry of transition metals and main group elements (included, but not limited to, titanium and phosphorus). Particular emphasis is placed on:

  • ü The synthesis and characterisation of organometallic compounds.
  • ü  The elucidation of questions pertaining to the nature of metal-ligand interactions: links between experiments and theory, epistemological implications (what is a chemical bond?).
  • ü  Reactivity studies, notably in small molecule activation (H2, CO2, P4).
  • ü  Applications to catalysis.

Current projects:

With P. Le Gendre (ICMUB) and G. Erker (WWU Münster), we are studying the properties of Cp2Ti+ or Cp2Zr+ cations stabilised by a phosphido (PR2-) or amido (NR2-) ligand. These complexes contain a Lewis acid and a Lewis base inside the same molecule, which enables them to activate organic substrates (H2, CO2…)in a cooperative manner (acid-base cooperativity).

This work has shown that Ti-P bonds could be cleaved homolytically to generate a Ti(III) metalloradical and a phosphinyl radical (PR2). We now wish to harness this reactivity and prepare diradical catalysts which could act cooperatively (radical cooperativity). To this end, we are developing new ligand frameworks in order to stabilise these reactive species.

Other ongoing projects include:

  • With P. Le Gendre (ICMUB), S. Dagorne (Unistra) and A. Auffrant (École polytechnique), the catalytic applications of “phosphasalen” complexes.
  • With M. Iglesias Alonso (Universidad de Zaragoza), the coordination chemistry of “N-heterocyclic olefin” complexes of Ti and Zr.
