text: A novel strategy for the immobilization of Wilkinson’s catalyst on silica
nanoparticles is presented, employing pyridyl linkers as anchoring groups. The
coordination binding of the catalyst to the pyridyl linker via ligand exchange
of the trans-phosphine group is verified by 1 D and 2 D solid-state NMR spectroscopy.
Catalytic activities are monitored by GC employing the hydrogenation of styrene
as model reaction, and the leaching properties as well as the robustness of the
catalyst are investigated. The resulting immobilized catalyst shows high catalytic
activity, which is within a factor of three comparable to the homogeneous catalyst,
and excellent stability in leaching tests. Finally, it is efficient to produce
hyperpolarization in solution by employing parahydrogen-enriched hydrogen gas
for hydrogenation.
