摘要：

Treatment of the tethered bis(2-cyclopentadienyl)phenylphosphine compound bis(2-cyclopentadienylethyl)phenylphosp (1) produces moderate yields (40-50%) of the ferrocene complex PPh(CH2CH2-eta5-C5H4)(2)Fe (2). Reaction of 2 with Me,NO in tetrahydrofuran gives the phosphine oxide O=PPh(CH2CH2-eta5-C5H4)(2)Fe (3) whereas treatment with the metal complexes trans-PdCl2(PhCN)(2), cis-PtCl(2()PhCN2), Fe-2(CO)(9), and Mo(CO)(5)(THF) give the corresponding di- or tri-metallic complexes trans -PdCl2[PPh(CH2CH2 eta5 -C5H4)(2)Fe](2) (4), cis-PtCl2[PPh(CH2CH2-(5)(eta)-C5H4)(2)Fe](2) (5), (OC)(4)FePPh(CH2CH2-(5)(eta)-C5H4)(2)Fe (7), and (OC)(5)MoPPh(CH2CH2 eta5-C5H4)(2)Fe (8), respectively, in which 2 is acting as a neutral two-electron-donor phosphine ligand. The electrochemistry of complexes 2, 3, 4, 5 and 7 have been investigated and complexes 3, 4 and 7 have been characterised further by X-ray crystallography. (C) 1999 Elsevier Science S.A.
