Latest Patents

Christine Sui-Seng holds a patent for "Iron(II) catalysts containing diimino-diphosphine tetradentate ligands and their synthesis." This patent describes new hexa-coordinate iron (II) complexes that comprise a tetradentate ligand with donor atoms of nitrogen and phosphorus. These complexes are demonstrated to be effective catalysts for the hydrogenation of ketones, aldehydes, or imines, leading to the production of alcohols or amines. Additionally, they facilitate the asymmetric hydrogenation of prochiral ketones or imines, resulting in non-racemic alcohols or amines. The hydrogen source can vary, including hydrogen gas or hydrogen-donating molecules such as isopropanol or formic acid mixed with an amine, depending on the catalyst's structure. The preparation of these catalysts typically involves a reaction using phosphine and diamine precursors, templated by the iron ion.
