Homogeneous Catalysis

Posted on 04/23/2009 by jags

The group is engaged in the synthesis and chemistry of cage compounds incorporating boron, carbon and transition metals which are usually bonded by S, P, and B-H bonds from the cluster. The spatial and electronic caracteristics of the cluster provide a unique and elegant way to pursue specific targets such as homogeneous catalysis.  catalysis1

 
 
So, the group has succeded in the construction of a number of half- and full-sandwich metallacarborane species and the evaluation of their potential applications as catalysts for Ziegler-Natta olefin polymerization, cyclopropanation reactions, alkene hydrogenations, and Kharasch catalysis reactions to the moment. Part of this research is done in collaboration with the University of Liege.
