A sterically hindered ferrocene-based bidentate diphosphine ligand widely used in homogeneous catalysis. Commonly employed with palladium, nickel, rhodium, iridium and other transition metals for Suzuki-Miyaura, Buchwald-Hartwig amination, Negishi, Kumada, Heck, Sonogashira and carbonylation reactions. Also used in pharmaceutical process development, asymmetric catalyst research, organometallic synthesis and fine chemical manufacturing.
