Alkane metathesis and related reactions via surface organometallic chemistry

Alkane metathesis and related reactions via surface organometallic chemistry

KCC, with its highly interdisciplinary structure, is ideally positioned to investigate and develop solutions for catalytic C-H and C-C bond formation reactions. Thanks to its pluridisciplinary nature, the strategy developed in KCC is to design catalysts based on the molecular understanding of the mechanism and the strong overlap between homogeneous, heterogeneous and biocatalysis.

By reacting well-defined molecular organometallic complexes or coordination compounds with surfaces of oxides or metals, one usually obtains well-defined catalytic species. With this approach, not only the reaction mechanism can be studied by isolating the elementary steps, but also new catalytic reactions are able to be discovered. This would not be possible with simple homogeneous systems without the new approach. The strategy will not only concern the design by surface organometallic chemistry on oxides, but also SOMC on metals and the mixed approach (SOMC /metal/oxide e.g. synthesis of core shell of metals particles).

In the low temperature range, metathesis of alkane will be one of the main reactions to target. The objective will be to reach an increase of the rate by a factor of 103 in the next six years. This will be achieved by understanding the elementary steps of the mechanism as well as the deactivation process. Additionally, several other goals to be achieved along with above reaction are metathesis of cyclic alkanes, ring opening metathesis of cyclic alkanes, cross metathesis of cyclic and acyclic alkanes and cross metathesis of cyclic and acyclic alkanes.
