  名称：

  New rhenium(I) compounds containing the donor–acceptor diphosphine ligands 2-(ferrocenylidene)-4,5-bis(diphenylphosphino)4-cyclopenten-1,3-dione (fbpcd) and 2-(3-ferrocenylprop-2-ynylidene)-4,5-bis(diphenylphosphino)4-cyclopenten- 1,3-dione (fpbpcd): Electrochemical behavior, MO properties, and X-ray diffraction structure of fac-BrRe(CO)3(fpbpcd)

  摘要：

  Displacement of the labile THF molecules in BrRe(CO)(3)(THF)(2) (1) by the diphosphine ligands 2-(ferrocenylidene)-4,5-bis(diphenylphosphino)4-cyclopenten-1,3-dione (fbpcd) and 2-(3-ferrocenylprop-2-ynylidene)-4,5-bis(diphenylphosphino)4-cyclopenten-1,3-dione (fpbpcd) yields the mononuclear compounds fac-BrRe(CO)(3)(fbpcd) (2) and fac-BrRe(CO)3(fpbpcd) (3). respectively. The new ligand fpbpcd ligand has been synthesized from 3-ferrocenylpropynal and the parent diphosphine ligand 4,5-bis(diphenylphosphino)-4-cyclopenten-1,3-dione (bpcd) through a Knoevenagel condensation, 2 and 3 have been isolated and fully characterized by IR and NMR spectroscopies (H-1 and P-31), ESI mass spectrometry, and X-ray diffraction analysis in the case of 3. The electrochemical properties of compounds 2 and 3 have been examined by cyclic voltammetry, and the nature of the HOMO and LUMO levels in these systems has been confirmed by MO calculations at the extended Huckel level. The redox and MO data are discussed relative to the redox and orbital properties of related functionalized diphosphines based on the bpcd platform. (C) 2009 Elsevier Ltd. All rights reserved.
