A sterically congested 1,2–diphosphino–1'–boryl–ferrocene: synthesis, characterization and coordination to platinum

Abstract : A new class of tritopic ferrocene-based ambiphilic compound has been prepared by assembling diphosphino- and boryl-substituted cyclopentadienides at iron. The presence of five sterically demanding substituents on the ferrocene platform induces conformation constraints, as apparent from XRD and NMR data, but does not prevent chelating coordination to platinum. The Lewis acid moiety is pendant in both the free ligand and the platinum complex.
