Selected olefin metathesis reactions that are expected to be particularly susceptible to confinement effects will be studied. Both the influence of the pore surface (polar, non-polar, protic, aprotic) and the pore size, geometry and tortuosity of various mesoporous systems in combination with differently functionalized olefins (polar, non-polar, protic, aprotic) on the reactivity of N-heterocyclic carbene complexes of Mo-/W-imido- and W-oxo-alkylidenes immobilized in these mesoporous systems will be scrutinized.

Research Questions

  • What is the influence of different functional surface groups (polar, non-polar, protic, aprotic) and the size, geometry and tortuosity of mesoporous systems in combination with different olefins (polar, non-polar, protic, aprotic) on the reactivity of Mo/W imido/oxo alkylidene NHC catalysts selectively immobilized inside these mesoporous systems in macrocyclization reactions?
  • How do confinement and the related diffusion issues influence macrocyclization efficiency and Z-selectivity?
  • Can the concept be extended to other olefin metathesis reactions?
