(S,S)-F-BINAPHANE is a chiral, ferrocene-based bisphosphine ligand. Its structure features a ferrocene core symmetrically substituted with two (S)-4,5-dihydro-3H-dinaphtho[2,1-c:1',2'-e]phosphole units, which are electron-rich and sterically demanding. This configuration endows the ligand with a well-defined, rigid chiral environment. This ligand is primarily employed in asymmetric catalysis, particularly in transition-metal-catalyzed reactions. It has demonstrated high efficiency and enantioselectivity in hydrogenation reactions, such as the asymmetric hydrogenation of functionalized olefins, ketones, and imines. The ferrocenyl backbone and the binaphthyl-derived phosphole moieties contribute to its stability and unique stereocontrol properties, making it a valuable tool for the synthesis of chiral pharmaceutical intermediates and fine chemicals. As a specialized chiral ligand, (S,S)-F-BINAPHANE is not a commodity chemical but a high-value research and development reagent used in academic and industrial laboratories focused on asymmetric synthesis. Its handling requires standard precautions for air- and moisture-sensitive organometallic compounds.
