Title: Gunther Oehme: Innovator in Hydrogenation Catalysts
Introduction
Gunther Oehme, based in Rostock, Germany, is a distinguished inventor with two significant patents to his name. His contributions primarily focus on the realm of chemical innovations, specifically in the production and application of advanced ligands for catalysts used in hydrogenation processes.
Latest Patents
Oehme's latest patents demonstrate his expertise in the field. The first, titled "Polymeric diphosphine ligands for homogeneously soluble hydrogenation catalysts, process for the production thereof and use," introduces molecular weight-enlarged, homogeneously soluble ligands that feature homochiral active centers of bis(3,4-diarylphosphinyl)pyrrolidines. These ligands are particularly beneficial for creating catalysts intended for enantioselective reactions.
His second patent, "Method of producing aryl-substituted, amino-acylated phosphonic-acid," outlines a method for producing aryl-substituted, amino-acylated phosphonic-acid derivatives. This process employs metal complexes of chiral amphiphilic ligands, where α-N-acyl-protected, β-substituted alkene phosphonate derivatives undergo asymmetrical hydrogenation in the presence of a chiral rhodium catalyst. The innovative micelle-forming catalyst facilitates the hydrogenation of unsaturated phosphonic-acid derivatives in water, achieving high reaction rates and excellent enantiomeric excesses.
