New lanthanide metal based transformations in organic and organometallic chemistry
My research is at the interface of organic and organometallic chemistry using powerful zero-valent lanthanide metals as reagents. In recent years, the focus has been on the synthesis of divalent lanthanide metallocenes bearing aryl-substituted cyclopentadienyl ligands (for example C5Ph5 or C5Ph4H). Recently, we have found a straight-forward synthesis via selective carbon-phosphorus bond activation in cyclopentadiene-phosphine precursors. C-F bond activation is currently a hot topic and we have shown that lanthanide metals can be highly efficient reagents for the single defluorination of trifluoromethylated benzofulvenes. In the presence of electrophiles, this process provides access to new difluoralkenes in a highly regio and stereoselective manner.
1/ Lanthanides in organic synthesis :
Using easy to handle, non-toxic lanthanide metals as reagents in organic synthesis has already provided new transformations or simplified reaction procedures. A current focus is on the selective C-F bond activation in various fluorine-containing organic molecules.
2/ Organolanthanide chemistry :
The synthesis of new divalent and trivalent organolanthanide complexes bearing polyarylcyclopentadienyl ligands is currently under investigation, especially by breaking selectively C-X bonds, e.g. C-F, C-P, … The reactivity, luminescence and magnetic properties of new complexes are studied.
3/ Catalysis :
New organic transformations based on visible light photocatalysis (with Dr. Alexis Prieto, ICGM) or earth-abundant transition metals (with Dr. Marc Taillefer, ICGM) are investigated.
