Address and map
The research activities of the Laboratoire de Chimie de Coordination at ULP-Strasbourg concern the molecular chemistry of the transition elements and include the interface between transition metals and main-group elements. They involve the synthesis of air-sensitive compounds using Schlenk techniques and the use of various spectroscopic methods. The objectives are to prepare new molecules of fundamental interest and/or which have potential applications in homogeneous or heterogeneous catalysis.
New Polytopic Ligands and their metal complexes: selective coordination, dynamic and hemilabile behaviour, chirality (Ru, Rh, Pd, Pt..). Applications to the reversible fixation of small molecules (e.g. CO) and in homogeneous catalysis (hydrogenation-transfer, co-oligomerisation olefins/CO).
Metal Complexes of Functional Enolates. Applications of phosphino enolate complexes in homogeneous catalysis: reversible fixation and catalytic activation of CO2 (Pd), ethylene oligomerisation (Ni), alcane activation (Rh), hydrogenation-transfer of ketones (Ru).
Bimetallics with Silicon Ligands. Synthesis and reactivity of heterometallic complexes containing a metal-silicon bond. Unusual hemilabile behaviour of alcoxysilyl ligands. Metal-silylene complexes. Applications to the catalytic dehydrogenative coupling of stannanes, the co-oligomerisation olefins/CO and to sol-gel chemistry.
Molecular Clusters. Synthetic methodologies for the preparation of low oxidation-state heterometallic complexes containing ligands such as CO, CN, isonitriles, phosphines, hydrocarbons,... Applications of the isolobal analogy, use of assembling ligands. Reactivity based on metallosite selectivity (metal recognition) and/or cooperativity effects between adjacent metal centres (synergistic effects). Applications to the preparation of hybrid materials (sol-gel route) and of new heterogeneous bimetallic catalysts.
