    trinuclear species. Under CO atmosphere the clean formation of [ReH(CO)5] and [Re3H(μ-H)(CO)13]- has been recognized. The anion 2 is formed (even if in lower yields) also by reaction of [Re2H2(μ-H)(CO)8]- with “Re2(CO)9(THF)”, obtained by treatment of [Re2(CO)10] with Me3NO in THF. A 13C NMR investigation has clarified that such “Re2(CO)9(THF)” reagent is indeed a mixture of three eq-[Re2(CO)9L] species, containing

  • 1,2-<i>eq,eq</i>-[Re<sub>2</sub>(CO)<sub>8</sub>(THF)<sub>2</sub>]:  A Reactive Re<sub>2</sub>(CO)<sub>8</sub> Fragment That Easily Activates H−H and C−H Bonds
    作者:Lucia Carlucci、Davide M. Proserpio、Giuseppe D'Alfonso

    日期:1999.5.1
    The reaction of [Re-2(mu-H)(2)(CO)(8)] (1) with diazomethane at 193 K in THF-d(8) gives the unstable [Re-2(mu-H)(mu-CH3)(CO)(8)] derivative (2) containing a methyl group arising from the insertion of CH2 into a Re-H-Re bond. Isotopic perturbation of the equilibria by partial deuteration demonstrated that the methyl bridges the Re-Re bond in an unsymmetrical way, with a fast exchange between one agostic and two terminal C-H bonds. At temperatures higher than 253 K, 2 decomposes, in THF solution, with CH4 elimination to give the novel red complex 1,2-eq,eq-[Re-2(CO)(8)(THF)(2)] (3), which was characterized by NMR spectroscopy and X-ray analysis. In the solid form a staggered conformer of Ca symmetry was found. C-13 NMR analysis revealed the presence, in wet THF, of the aquo complexes [Re-2(CO)(8)(THF)(H2O)] (4) and [Re-2(CO)(8)(H2O)(2)] (5), whose formation is favored at low temperature (Delta H degrees for the formation of 5 from 4: -14.4(2) kJ mol(-1)). In solution, due to the lability of the THF ligands, 3 behaves as a "lightly stabilized" Re-2(CO)(8) fragment, capable of activating different E-H bonds. Reaction with HCl in THF leads to [Re-2(mu-H)(mu-Cl)(CO)(8)], while with H-2 the unsaturated starting material [Re-2(mu-H)(2)(CO)(8)] is obtained. In THF solution, at room temperature, reactions with phenylacetylene, styrene, and acetaldehyde give the derivatives of C-H activation [Re-2(mu-H)(mu-C drop CPh)(CO)(8)], [Re-2(mu-H)(mu-CH=C(H)Ph)(CO)(8)], and [Re-2(mu-H)(mu-eta(2)-C(Me)O)(CO)(8)]. Moreover, the activation of an sp(3) C-H bond in ethyl acetate occurs slowly when 3 is dissolved in the reactant itself, the resultant product being [Re-2(mu-H)(mu-eta(2)-CH2C(O)OEt)(CO)(8)].
