Prof. J.-F. Carpentier - Dr S. Guillaume - Dr E. Kirillov - Dr Y. Sarazin

The research activities of the OCP group focus chiefly on the design of well-defined organometallic complexes of oxophilic metals (alkaline earths; rare earths; groups 4 (Ti-Hf) 12 (Zn), 13 (Al-In), 14 (Ge- Pb)) and their utilisation as molecular catalysts to promote atom-efficient reactions. We also nurture a keen interest in polymer chemistry towards the elaboration of industrially and biomedically relevant polymer materials.

Polymerisation catalysis has long been an expertise of our group. We have a particular emphasis on the ring-opening polymerisation (ROP) of mainstream or specifically designed bio-resourced cyclic esters and carbonates to produce degradable polymers, and on the Ziegler-Natta polymerisation of olefins, styrenics and dienes, to understand the intimate mechanisms of stereocontrolled processes and for the production of industrially-relevant materials. Some properties of these polymers are also investigated, either as bulk materials for polyolefins, or as specialty polymers for medical and biomedical applications for polyesters/polycarbonates. We have also been developing more recently the use of ring-opening metathesis polymerization (ROMP) coupled with cross-metathesis catalysis to access new pre-polymers towards highly topical non-isocyanate polyurethane (NIPU)-type materials and silyl-modified polymers (SMPs).

Our group has also a strong experience in catalysis for fine chemicals synthesis. Long orientated towards carbonylation reactions (hydroformylation), we have also recently started implementing homogeneous alkaline-earth and rare-earth catalysts in organic transformations such as the hydroamination and hydrophosphination of alkenes for the creation of C–N and C–P bonds, or dehydrogenative couplings to create E–E’ bonds between heteroelements. This constitutes a prolific area of our research.
