  摘要：

  The title compounds were prepared by treating Fe(PR(3))(2)Cl-2 or Fe(R(2)P(CH2)(n)PR(2))Cl-2 with allylmagnesium chloride. Some of them were also made by reaction of Fe(PR(3))(2)Cl-2 with isopropylmagnesium chloride, or with active-magnesium and allyl chloride, or by reaction between tris(eta(3)-allyl)iron and bis(dimethylphosphino)ethane. The new compounds were characterized by NMR spectroscopy and shown to be formed as a mixture of two isomers that differ in the mutual arrangement of the two allyl groups. The reactions of the bis(allyl)iron compounds with 1,3-dienes were studied: complexes containing eta(4)-1,3-C4H6, eta(4)-1-C3H5C4H5 or eta(5)-l-ethylcyclohexadienyl groups were isolated from the reaction with 1,3-butadiene. The reaction between (eta(3)-C3H5)(2)Fe((Pr2PC2H4PPr)-Pr-i-Pr-i(2)) and 1,3-cyclohexadiene gave (eta(5)-cyclohexadienyl)Fe((Pr2PC2H4PPr2)-Pr-i-Pr-i)H.

  mechanisms of protonation and substitution of trans-[FeH(X)(diphosphine)2][X = Cl or Br, diphosphine = Et2PCH2CH2PEt2(depe) or Ph2PCH2CH2PPh2(dppe)] have been investigated in tetrahydrofuran at I= 0.1 mol dm–3([NBun4][BF4]) and 25 °C. In the presence of acid, HX, loss of phosphine and formation of [FeX2(diphosphine)] occurs by a variety of pathways dependent upon the nature of the phosphine. When diphosphine

  contrast, the mechanisms of the reactions of the nucleophiles L = CO, MeCN, or PhCN depend on the iron complex. Substitution of the bridged-dinitrogen ligand in trans-[FeCl(depe)2}2(µ-N2)]2+ occurs, in general, by two parallel pathways. After initial phosphine chelate ring opening the vacant site thus generated can be attacked either by a molecule of solvent or the nucleophile. Subsequent loss of dinitrogen
