  名称：

  (η5-C5H5)-Ring alkylation reaction with the C5H5 anion: towards the construction of tri-Fe complex Fe{[μ,η5:η4-5-exo-(1′-C5H4)C5H5]Fe(CO)2(PPh3)}2

  摘要：

  The reaction of (eta (5)-C5H5)Fe(CO)(2)I with C5H5M (M = Na, Li) in the presence of PPh3 gives the Cp-ring alkylation eta (4)-Fe products 10a,b. The compounds 10a,b could be deprotonated with n-BuLi to generate 12. When 12 reacts with FeCl3, the reaction produces the tri-Fe complex 6, Fe{[mu,eta (5):eta (4)-5-exo-(1'-C5H4)C5H5]Fe(CO)(2)(PPh3)}(2), whose hydride abstraction with Ph3CPF6 results in 13, [Fe [mu,eta (5):eta (5)-1-(1'-C5H4)C5H4]Fe(CO)(2)(PPh3)}(2)][PF6](2). A similar strategy was applied in the preparation of penta-Fe complex 15, Fe[mu-eta (5)-C5H3-1,3-{(C5H5-5'-exo-,eta (4))Fe(CO)(2)(PPh3)}(2)](2), which has four eta (4)-Fe arms attached to a ferrocene core. The compound 12, upon treatment with the W(CO)(3)(EtCN)(3) then MeI sequence, gives the dimetallic eta (4)-Fe, eta (5)-W complex 17. The endo-hydride of 17 could be abstracted with Ph3CPF6 to result in 18 whose reaction with C5H5Na proceeds smoothly with the Cp-ring alkylation and gives eta (4)-Fe products 19a,b. Treatment of 19a,b with n-BuLi, followed by the W(CO)(3)(EtCN)(3) then Mel sequence yields the trimetallic eta (5)-W, eta (4)-Fe, eta (5)-W complex 20. (C) 2001 Elsevier Science B.V.
