Research (click on the links to obtain more details)

 The major thrust of our research is on the design of new generations of highly reactive transition-metal complexes that are prone to provide low activation energy pathways for key elementary substrate transformations in relevance to organic synthesis. The performances of our complexes in terms of activity and selectivity are optimized by suitable combinations of efficient (stereo-directing) ligands, and appropriate leaving groups.
Our main area of expertise is on late transition metals, with particular emphasis on:

• The chemistry of ruthenium, centred on Ru(0) and Ru(II) complexes.
• The chemistry of manganese, centred on Fischer type carbene complexes.
  

 In line with these research directions, and beyond the scope of these metals, a new facet of our activity is the engineering of original ligands based on N-heterocyclic carbenes (NHC). These include :

• Anionic and functionnalized N-heterocyclic carbenes
  
• Multidentate NHC-containing ligands
  

The projects briefly outlined above are dealing with various types of carbon-carbon bond forming reactions, including C-H olefin coupling and olefin metathesis.

 In addition to classical spectroscopic and crystallographic structure determination methods, our group is also developing experimental charge density analyses, allowing a direct visualization of bonding electrons.
