Description of the group

The SRCO team broadly aims at the design and reactivity of novel organometallic complexes for small molecules activation (H2, CO2) and use in homogeneous catalysis, with a special emphasis on sustainable catalytic processes. 

Past/current industrial colloborations: Corbion-Purac Corp. (lactide polymerization), SNF Corp. (biodegradable hydrophilic polymers)

Our team welcomes internship applications at the Master level, potential candidates interested in PhD studies as well as post-doctoral candidates.   

Research topics

  • oxophilic metal complexes (groups 2, 4, 12 and 13) with N-heterocyclic carbenes (NHCs) for novel reactivity of fundamental interest,,
  • Small molecules (H2, CO2) activation (H2, CO2) with highly electrophilic organometallics based on Al(III), Zn(II) and Mg(II) salts,
  • Polymerization catalysis of cyclic esters/carbonates using organometallics for the production of biomaterials,
  • Organometallic complexes of Au(I)/Au(III) for use in homogeneous catalysis.
