Treatment of the tethered bis(cyclopentadienyl)-phosphine compound bis(2-cyclopentadienylethyl)phenylphosphine (1) produces moderate yields (40-50%) of the ferrocene complex PPh(CH2CH2-η5-C5H 4)2Fe (2). Reaction of 2 with Me3NO in tetrahydrofuran gives the phosphine oxide O=PPh(CH2CH2-η5-C5H 4)2Fe (3) whereas treatment with the metal complexes trans-PdCl2(PhCN)2, cis-PtCl2(PhCN)2, Fe2(CO)9, and Mo(CO)5(THF) give the corresponding di- or tri-metallic complexes trans-PdCl2[PPh(CH2CH2-η5-C 5H4)2Fe]2 (4), cis-PtCl2[PPh(CH2CH2-η5-C 5H4)2Fe]2 (5), (OC)4FePPh(CH2CH2-η5-C 5H4)2Fe (7), and (OC)5MoPPh(CH2CH2-η5-C 5H4)2Fe (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.
