Tuning C6/C8 selectivity of Cr-catalyzed oligomerization of ethylene by exploiting confinement effects
– New project since July 2022 –
In this funding period, we will transfer the concept of confinement-governed olefin-metathesis-based macrocyclization to confinement-governed oligomerization of small molecules. Here, the main aim is to exploit confinement effects to selectively produce trimeric or tetrameric products from ethylene, i.e., 1-hexene or 1-octene, respectively. To this end we will use immobilized Cr N-heterocyclic carbene catalysts that are robust and promising alternatives to existing Cr-complexes. We aim to exploit constrained geometries to selectively stabilize those transition geometries that lead to desired end products and we will leverage acidity, polarity and π-donating abilities of the support.
