    compounds which have unconventionally long metal ligand distances, are found to react very differently with CO as a substrate. The 4f(3) complex (C(5)Me(5))(3)Nd reacts with CO to form a nonclassical carbonium ion complex, (C(5)Me(5))(2)Nd(O(2)C(7)Me(5)), which contains a three-coordinate planar carbon. (C(5)Me(5))(3)U reacts with CO to form an even more crowded CO adduct through a reaction type never

    Bis(pentamethylcyclopentadienyl)calcium, (C5Me5)2Ca, can be made by the reaction of Ca[N(SiMe3)2]2 with C5Me5H in toluene. It undergoes cyclopentadienyl ring metathesis with tris(cyclopentadienyl)lanthanide complexes, Cp3Ln (Ln = La, Nd, Sm) in toluene to generate the mixed ring complexes (C5Me5)2LnCp. The X-ray crystal structure of (C5Me5)2NdCp shows that the complex is a sterically crowded monomer

    reactions with (C5Me5)3Ce and (C5Me5)3U gave a mixture of C5Me5SPh and (C5Me5)2 as byproducts. PhSSPh reactions with the lanthanide nitrile adducts, (C5Me5)3Ln(NCCMe3)2 (Ln = La, Ce) and (C5Me5)3Nd(NCCMe3), formed [(C5Me5)2Ln(SPh)(NCCMe3)]2 and only C5Me5SPh as the byproduct. PhSeSePh reactions paralleled the PhSSPh results, but reactions of PhTeTePh with (C5Me5)3La, (C5Me5)3Sm, and (C5Me5)3La(NCCMe3)2

  • Defining Reactivity Differences in Sterically Crowded (η<sup>5</sup>-C<sub>5</sub>Me<sub>5</sub>)<sub>3</sub>M Complexes Based on Metal Size and Lanthanide vs Actinide Effects
    作者:Thomas J. Mueller、Gregory W. Nyce、William J. Evans
    DOI:10.1021/om101149z
    日期:2011.3.14
    Reactions between (eta(5)-C5Me5)(3)M and (eta(5)-O5Me5)(2)M'(mu-Ph)(2)BPh2 (M, M' = La, Ce, Pr, Nd, Sm, and U; M radius < M' radius) were examined to evaluate the relative steric crowding in the (C5Me5)(3)M series as a function of metal size and 4f vs 5f electron configuration. The sterically more crowded (C5Me5)(3)M complexes transfer (C5Me5)(-) to (C5Me5)(2)M'(mu-Ph)(2)BPh2 to generate less crowded (C5Me5)(3)M' products and (C5Me5)(2)M(mu-Ph)(2)BPh2 in mixtures with equilibrium constants in the range that allows all four components to be observed by NMR spectroscopy. The (C5Me5)(3)M to (C5Me5)(3)M' ratios depend on the difference in size of the two metals. Hence, (C5Me5)(3)Sm and (C5Me5)(2)La(mu-Ph)(2)BPh2 form a mixture with 99% (C5Me5)(3)La and 1% (C5Me5)(3)Sm, but the analogous reaction with (C5Me5)(2)Nd(mu-Ph)(2)BPh2 contains 90% (C5Me5)(3)Nd and 10% (C5Me5)(3)Sm. In analogous reactions with (C5Me5)(2)U(mu-Ph)(2)BPh2 and (C5Me5)(3)Ln lanthanide complexes, a size dependence is also observed, but the (C5Me5)3Ln complexes are favored over (C5Me5)(3)U to a greater extent than expected based on size differences.
  • The Trivalent Neodymium Complex [(C5Me5)3Nd] Is a One-Electron Reductant!
    作者:William J. Evans、Gregory W. Nyce、Robert D. Clark、Robert J. Doedens、Joseph W. Ziller

    A Se22- complex, Ph3 P, and (C5 Me5 )2 are formed in the reduction of Se=PPh3 by the NdIII complex [(C5 Me5 )3 Nd] [Eq. (a)]. The latter is thus reminiscent of [(C5 Me5 )3 Sm], which, however, appears to be a stronger reductant than [(C5 Me5 )3 Nd]. This suggests that the reductive reactivity of [(C5 Me5 )3 Ln] complexes can be tuned by varying the size of the metal atom.
