Wilkinson's catalystOlefin hydrogenationRhodium nanoparticlesImmobilized catalysts can be obtained by using a linker to bind a homogeneous catalyst to a solid support. Ideally, immobilized catalysts combine the advantages of homogeneous and heterogeneous catalysts. Porous supports such as silica result in ...
The hydrogenation of β pinene over homogeneous and anchored Wilkinson's catalysts was studied. Phosphotungstic acid was used to anchor the Wilkinson catalyst to an alumina support by an interaction between the heteropoly acid and the rhodium atom of the complex. The hydrogenation of β pinene over...
The resulting material was characterized by solid-state NMR spectroscopy, X-ray photoelectron spectroscopy, thermogravimetry, and TEM before testing the catalytic efficiency of the catalyst. Excellent hydrogenation efficiency with yields in the range of 85–99 % could be obtained with these new NDs...

The formula of Wilkinson's catalyst provides a method for selectively breaking double bonds at the molecular level. Review the formula, structure,...
The historic importance of this compound is that it was the first homogeneous hydrogenation catalyst to be discovered, and a very efficient one at that, better than the existing catalysts and operating at 25 °C under normal atmospheric pressure. In Wilkinson’s catalyst, the rhodium has a 16-...
