  Synthesis, Molecular Structure, and Reactivity of Organolanthanide Fluoride Complexes, [{(Me₃Si)₂C₅H₃}₂Ln(μ-F)]₂ (Ln = La, Nd, Sm, Gd) and [(C₅H₅)₂Ln(μ-F)(THF)]₂ (Ln = Y, Yb)

  摘要：

  Treatment of Me3NHF with I equiv of [(Me3Si)(2)C5H3](3)Ln or (C5H5)(3)Ln in THF gave [{-(Me3Si)(2)C5H3}(2)LnF](2) (Ln = La (1), Nd (2), Sm (3), Gd (4)) or [(C5H5)(2)LnF(THF)](2) (Ln = Y (5), Yb (6)) in moderate to good yield. All of them were fully characterized by elemental analyses, spectroscopy, and X-ray analyses. Compound 3 reacted with Na, AlCl3, (C6H5)(3)-SiOH, and 2,6-(Pr2C6H3OH)-C-i to form [(Me3Si)(2)C5H3](2)Sm(THF), [{(Me3Si)(2)C5H3}(2)SmCl](2), [(C6H5)(3)SiO](3)Sm(THF)(3) (7), and [2,6-(Pr2C6H3O)-C-i](3)Sm(THF)(3) (8), respectively. The molecular structures of [{(Me3Si)(2)C5H3}(2)SmCl](2), 7, and 8 were confirmed by X-ray diffraction study. The 3/NaH system can convert C6H5Br into C6H6 in 32% yield.
