摘要：

Novel boronato-functionalized ferrocenylphosphine ligands 3a-c have been synthesized from (S,R)-1,1'-bis(diphenylphosphino)-2-[1((1-hydroxy-2-phenyl)amino)ethyl]-ferrocene (2). These ligands form stable ligand-metal adducts with Rh(I) complexes that are catalytically active in hydrogenation and hydroformylation reactions. The square-planar metal complex Pt(2)Me)I exhibits a structure that appears well-suited to support secondary interactions between the Lewis acidic boron functionality and Lewis basic sites of functionalized, coordinated alkenes.
