  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.

  Synthesis and crystal structure of an organolanthanide fluoride, [{(Me3Si)2C5H3}2Sm(μ-F)]2

  摘要：

  Treatment of [(Me3Si)(2)C5H3](2)SmI(THF) with stoichiometric amounts of AgSbF6 in dry diethyl ether, or reaction of [(Me3Si)(2)C5H3](3)Sm with one equivalent of Me3NHF in dry 1,2-dimethoxyethane afforded the dimeric complex [{(Me3Si)(2)C5H3}(2)Sm(mu-F)](2) in good yield, which represents the first structurally characterized example of a fluoride-bridged organosamarium complex. It crystallizes in space group P2(1)/n with a = 12.215(1)Angstrom, b = 16.028(1)Angstrom, c = 15.677(1)Angstrom, beta = 99.78(1)degrees, V = 3025(2)Angstrom(3), and Z = 2 for D-calcd = 1.292gcm(-3). Least squares refinement of the structural model based on 5471 reflections (\F\>6.0 sigma\F\) converged to R-F = 0.040. The average Sm(1)-F distance is 2.302(3)Angstrom.
