Abstract

The synthesis of a bulky chelating bis(phosphine) ligand, 1,2-bis(dinbutylphosphino)ethane, nBu2PCH2CH2PnBu2 (1) (Bu = Butyl = C4H9) (DBPE) is reported. This ligand was coordinated to iron by treatment with FeCl2 to yield Fe(DBPE)2Cl2 (2) which is an important precursor of a variety of σ-acetylide complexes, e.g. Fe(DBPE)2 (CCC6H5)2 (3). Complex 2 is paramagnetic in solution at room temperature and diamagnetic in the solid state. The optical absorption spectrum of 3 shows strong absorptions associated with π-π{black star} transition of the acetylenic unit.
