    Synthesis and Characterization of BIS(Cyclopentadienyl)Yttrium and Lanthanide Tetrazolate Complexes: Crystal Structure of [(C5H5)2Y(μ-η12-N4CPh)]2
    摘要:
    Reaction of Cp(3)Ln (Cp = C5H5) and 5-phenyl-1H-tetrazole (HTz) in THf (tetrahydrofUran) affords the complexes [Cp(2)Ln(mu=Tz)](2) [Ln = Y (1), Ho (2), Er (3), Yb (4)], which were characterized by elemental analyses, infrared spectra and mass spectra. X-ray single crystal investigation shows that complex (1) is a centrosymmetric tetrazolate-bridged dimer in which each yttrium(III) ion is coordinated by two cyclopentadienyl groups and three nitrogen atoms of the bridging Tz ligands in a distorted trigonal-bipyramidal geometry. The bridging unit Y2N6 is in a chair conformation, which is different front the planarity in the known isostructural complexes [(C5H4CH3)(2)Ln(mu-eta(1):eta(2)-Tz)](2) (Ln = Yb, Dy, Gd).

    Treatment of [Cp2LnNHPy]2 (Py = 2-pyridyl) (1) with 4-nitrophenyl isocyanate gives the unexpected complexes Cp2Ln[η2:η1-PyNCON(C6H4NO2-4)CONHC6H4NO2-4] (Ln = Yb (5a), Er (5b)) as the main product regardless of the equivalency of isocyanate reagent employed. The more bulky isocyanate (2,6-iPr2C6H3NCO) also undergoes double insertion into 1, affording Cp2Ln[η2:η1-PyNCON(C6H3iPr2-2,6)CONHC6H3iPr2-2,6]

    The ethyl substituted aluminum hydroxide LAlEt(OH) (2; L = HC[C(Me)N(Ar)]2; Ar = 2,6-iPr2C6H3) was prepared by the hydrolysis of LAlEt(Cl) (1) in the presence of a N-heterocyclic carbene. The reaction of 2 with Cp2ZrMe2 in toluene afforded LAlEt(μ-O)ZrMeCp2 (3) by evolution of methane, while the reaction of 2 with Cp3M in THF led to the intermolecular elimination of HCp and formation of LAlEt(μ-O)M(THF)Cp2

    Treatment of the thermally stable aminosilylene Si[N(CH2tBu)}2C6H4-1,2] [= Si(NN)] with a tris(cyclopentadienyl)- group 3 or -lanthanide metal compound LnCp3 (Cp = η5-C5H5 and Ln = Y or Yb) in toluene at ambient temperature afforded the first earliest transition or f-block metal-silylene complexes [LnCp3Si(NN)}]·C7H8 (Ln = Y (1) or Yb (2)), characterized by NMR spectroscopy and X-ray crystallography: complex 1 (monoclinic, space group P21/c (no. 14), a = 15.641(5), b = 15.895(7), c = 14.876(5) Å, β = 112.93(3), Z = 4, R1 = 0.067 for 6194 observed data), and2 (monoclinic, space group P21/c (no. 14), a = 15.635(3), b = 15.795(2), c = 14.842(2) Å, β = 112.87(2), Z = 4, R1 = 0.044 for 9829 observed data). The Ln atom in each of the isoleptic complexes 1 and 2 has distorted trigonal monopyramidal geometry, with the approximately trigonal silicon atom in the apical position. The Ln-Si bond length is 3.038(2) (1) or 2.984(2) Å (2).

  • Synthesis and controlled hydrolysis of organolanthanide complexes with mono- and dianionic benzimidazole-2-thiolate ligands

    Treatment of Cp3Er with one equivalent of benzimidazole-2-thiol (H2Bzimt) in THF affords the monoanionic HBzimt− complex Cp2Er(η2-HBzimt)(THF)2 (1). Reaction of Cp3Yb with two equivalents of H2Bzimt gives complex CpYb(η2-HBzimt)2(THF) (2) at room temperature. Treatment of Cp3Ln with three equivalents of H2Bzimt in reflux THF affords the homoleptic Ln(η2-HBzimt)3(THF)2 (Ln = Er (3), Y (4)). Cp3Ln reacts with 0.5 equivalents of H2Bzimt to afford the dianionic Bzimt2− complexes [(Cp2Ln)(THF)]2(μ-Bzimt) (Ln = Yb (5), Er (6), Dy (7), Y (8)) in good yields, in which the Bzimt2− ligand bridges the two metals in an μ-η2:η2 coordination mode. Interestingly, controlled hydrolysis of complexes Cp2Ln(η2-HBzimt)(THF)2, CpLn(η2-HBzimt)2(THF) and [(Cp2Ln)(THF)]2(μ-Bzimt) produces the same tetranuclear complexes [CpLn(μ3-OH)(μ-η1:η2-HBzimt)]4 (Ln = Yb (9), Er (10), Y (11)), indicating that the hydrolysis selectivity greatly depends on the number of coordinated cyclopentadienyl groups. All complexes were characterized by elemental analysis, spectroscopic properties and X-ray single crystal diffraction analysis.
    将 Cp3Er 与一当量的苯并咪唑-2-醇(H2Bzimt)在 THF 中处理,可得到单阴离子 HBzimt-络合物 Cp2Er(η2-HBzimt)(THF)2(1)。Cp3Yb 与两当量的 H2Bzimt 反应,在室温下得到复合物 CpYb(η2-HBzimt)2(THF)2 (2)。在回流 THF 中用三当量的 H2Bzimt 处理 Cp3Ln,可得到同色的 Ln(η2-HBzimt)3(THF)2 (Ln = Er (3),Y (4))。Cp3Ln 与 0.5 个等效当量的 H2Bzimt 反应,可以得到双离子 Bzimt2- 复合物 [(Cp2Ln)(THF)]2(μ-Bzimt)(Ln = Yb (5)、Er (6)、Dy (7)、Y (8)),产量很高,其中 Bzimt2- 配体以 μ-η2:η2 配位模式桥接两种属。有趣的是,络合物 Cp2Ln(η2-HBzimt)(THF)2、CpLn(η2-HBzimt)2(THF) 和 [(Cp2Ln)(THF)]2(μ-Bzimt)的受控解产生了相同的四核络合物 [CpLn(μ3-OH)(μ-η1:η2-HBzimt)]4 (Ln = Yb (9)、Er (10)、Y (11)),表明解选择性在很大程度上取决于配位环戊二烯基团的数量。所有配合物都通过元素分析、光谱特性和 X 射线单晶衍射分析进行了表征。

    The treatment of Cp3Ln with 1 equiv of N,N′-dicyclohexyl-N′′-phenylguanidine followed by reacting with butyllithium yields a series of novel guanidinate dianion complexes of heterobimetallic lanthanide−lithium with formula Cp2Ln[(CyN)2CNPh]Li(THF)3 (Ln = Yb (1a), Er (1b), Y (1c), Dy (1d)). Reactivities of these dianionic guanidinate complexes toward various electrophiles have been investigated. Reaction
