Heterogeneous Dinuclear Rhodium(II) Hydroformylation Catalysts-Performance Evaluation and Silsesquioxane-Based Chemical Modeling

Supported, air stable, and reusable hydroformylation catalysts have been prepared by immobilizing dinuclear rhodium(II) complexes bearing ortho‐metalated arylphosphane ligands on amorphous silica and mesoporous MCM‐41 supports by phosphane tethers. The oligosilsesquioxane model complex of the cataly...

Description
Summary:Supported, air stable, and reusable hydroformylation catalysts have been prepared by immobilizing dinuclear rhodium(II) complexes bearing ortho‐metalated arylphosphane ligands on amorphous silica and mesoporous MCM‐41 supports by phosphane tethers. The oligosilsesquioxane model complex of the catalytic site 1 has been prepared analogously and characterized by single‐crystal X‐ray diffraction analysis.
