Latest Patents
Friederike Freutel holds 1 patent for her invention titled "Iron(II) catalysts containing diimino-diphosphine tetradentate ligands and their synthesis." This patent describes new hexa-coordinate iron(II) complexes that include tetradentate ligands with donor atoms of nitrogen and phosphorus. These complexes are innovative as they serve as effective catalysts for the hydrogenation of ketones, aldehydes, or imines, leading to the production of alcohols or amines. Furthermore, they enable the asymmetric hydrogenation of prochiral ketones or imines, resulting in non-racemic alcohols or amines. The hydrogen source can vary, utilizing hydrogen gas or hydrogen-donating molecules such as isopropanol or formic acid combined with an amine, depending on the catalyst's structure. The preparation of these catalysts involves a reaction using phosphine and diamine precursors, templated by the iron ion.
