  Facile Syntheses of Unsolvated UI₃ and Tetramethylcyclopentadienyl Uranium Halides

  摘要：

  In the course of comparing the reaction chemistry of (C5Me5)(3)U, 1, and its slightly less crowded analogue (C5Me4H)(3)U, 2, new syntheses of Ul(3), (C5Me4H)(3)U, (C5Me4H)(3)UCl, 3, and (C5Me5)(3)UCl, 4, have been developed. Additionally, (C5Me4H)(3)Ul, 5, and (C5Me4H)(2)UCl2, 6, have been identified for the first time. A facile synthesis of unsolvated Ul(3) is reported that proceeds in high yield with inexpensive equipment from iodine and hot uranium turnings. Both Ul(3) and Ul(3)(THF)(4) react with KC5Me4H in toluene to make unsolvated (C5Me4H)(3)U in higher yield than in previous reports that involve reduction of tetravalent (C5Me4H)(3)UCl, 3. A more atom-efficient synthesis of complex 3 is also reported that proceeds from reduction of t-BuCl, PhCl, or HgCl2 by 2. Similarly, (C5Me4H)(3)U reacts with Phl or Hgl(2) to generate (C5Me4H)(3)Ul. These studies also provided a basis to improve the synthesis of (C5Me5)(3)UCl from 1 by employing t-BuCl or HgCl2 as the halide source. Like (C5Me5)(3)UCl, the (C5Me4H)(3)UCl Complex reacts with HgCl2 to form (C5Me4H)(2) and (C5Me4H)(2)UCl2, 6, but unlike (C5Me5)(3)UX (X = Cl or l), the less substituted (C5Me4H)(3)UX complexes do not reduce t-BuCl or PhX. The synthesis of 6 from (C5Me4H)MgCl-THF and UCl4 is also included.

  organoactinide (C5Me5)3UX complexes involving the in situ formation of borate salts is reported. Addition of BPh3 to (C5Me5)2UMeCl followed by KC5Me5 provides a much improved synthesis of (C5Me5)3UCl that presumably proceeds through a [(C5Me5)2UCl][MeBPh3] intermediate borate salt. Attempts to make (C5Me5)3UMe, the first tris(pentamethylcyclopentadienyl) metal alkyl complex, by reaction of BPh3 with (C5Me5)2UMe2

  报道了原子和时间效率高的合成方法，该方法合成了空间密集的有机act（C 5 Me 5）3 UX络合物，涉及硼酸盐的原位形成。将BPh 3添加到（C 5 Me 5）2 UMeCl中，然后添加KC 5 Me 5可以大大改善（C 5 Me 5）3 UCl的合成，该合成大概通过[（C 5 Me 5）2 UCl] [MeBPh 3 ]硼酸盐中间体。尝试做出（C 5 Me 5）3 UME，第一三（五甲基环戊二烯）金属烷基配合物，由BPH的反应3与（C 5我5）2 UME 2接着KC 5我5也是成功的，并且将产物通过X射线晶体学。在该反应系统中，通过可变温度NMR光谱和THF加合物的X射线晶体学证实了硼酸盐中间体[（C 5 Me 5）2 UMe] [MeBPh 3 ]的形成。
