Novel Catalysts for Asymmetric Olefin Hydrogenation: Low Cost, Low Toxicity, High Modularity

Princeton Docket # 12-2801 Catalytic asymmetric hydrogenation reactions are important to prepare single enantiomer drugs, agrochemicals and fragrances. Present technologies for such reactions involve catalysts based on iridium, rhodium, platinum, and ruthenium. These precious metals are expensive, toxic, have fluctuations in supply and pose environmental...
