Immobilization of a Modified Tethered Rhodium(III)-p-Toluenesulfonyl-1,2-diphenylethylenediamine Catalyst on Soluble and Solid Polymeric Supports and Successful Application to Asymmetric Transfer Hydrogenation of Ketones
Catalystimmobilization through covalent attachment onto a support is one strategy to provide recyclable systems. Here, soluble and surface-functionalized solid polymers were used as supports for a modified tethered rhodium(III)-p-toluenesulfonyl-1,2-diphenylethylenediamine [Rh(III)-TsDPEN] complex. The supportedcatalysts were applied to the asymmetric transfer hydrogenation of phenyl ketones in aqueous
