  Organochromium π-complexes—VI. The preparation of Cp′(η3-allyl)2Cr compounds and their reactions with donor ligands

  摘要：

  The title compounds have been prepared by reacting a Cp'CrCl2 or a (eta3-allyl)2CrCl species with either an allylmagnesium halide or a substituted cyclopentadienyllithium derivative. The compounds react further at room temperature to give the dinuclear species [Cp'(mu-eta3-allyl)Cr]2, and with P-donor ligands with reductive coupling of the allyl groups to give Cp'(eta2,eta2-1,5-hexadiene)CrPR3 species. Diene exchange is observed upon reacting the hexadiene compounds with butadiene or cyclohexadiene. The crystal structures of [Cp'(mu-eta3-C3H5)Cr]2, [(eta5-indenyl)(mu-eta3-C3H5)Cr]2, (eta5-indenyl) (eta2,eta2-1,5-hexadiene)CrP(OMe)3 and three compounds containing a 1,3-diene, viz. Cp(eta4-1,3-C4H6)CrPMe3, (eta5-Me5C5)(eta4-1,3-C4H6)CrCO and Cp(eta4-1,3-cyclohexadiene) CrP(OMe), have been established by X-ray diffraction.
