    A Hexamethyl Derivative of [9]Mercuracarborand-3:  Synthesis, Characterization, and Host−Guest Chemistry
    摘要:
    Hexamethyl[9]mercuracarborand-3, [(CH3)(2)C2B10H8Hg](3) (3), was isolated in 60% yield from the reaction of closo-1,2-Li-2-9,12-(CH3)(2)-1,2-C2B10H8 with mercuric acetate. The title compound was characterized by multinuclear NMR spectroscopy and its halide ion complexes by negative ion FAB mass spectrometry, Both 3 and its complexes are air-stable and soluble in poorly or noncoordinating solvents such as CH2Cl2 and toluene. Compound 3 crystallized from acetonitrile in the triclinic space group P (1) over bar with a = 13.362(6) Angstrom, b = 14.071(6) Angstrom, and c = 14.303(6) Angstrom, alpha = 105.15(1)degrees, beta = 95.77(1)degrees, and gamma = 110.14(1)degrees, V = 2383 Angstrom(3), and Z = 2. The final discrepancy indexes were R = 0.059, R(w) = 0.064 for 5987 independent reflections with (I > 3 sigma(I). Halide ion complexes of 3 were formed upon treatment of 3 with salts of the corresponding halide ions. The complexation behavior of 3 in acetone was studied by Hg-199 NMR spectroscopy, and the guest/host ratio of the resulting complexes has been established to be 1, 2, and 2 for chloride, bromide, and iodide, respectively.

    改进了含有外多面体BC和CC键的二十面体碳硼烷的合成。
    摘要:
    碳硼烷是富含硼的分子簇,具有电子特性,可通过正交方法进行顶点选择性修饰。我们报告了改进的功能化方法,利用正交化学在碳硼烷的富电子B顶点和贫电子C顶点处实现有效取代。通过使用具有富电子联芳基膦配体的钯基预催化剂,可以改善使用相应的格氏试剂在烷基和(杂)芳基上形成B顶点的功能,从而缩短了反应时间。重要的是,该方法对含有β-氢的基于烷基的格氏试剂具有耐受性。此外,在亲核芳香族取代(SNAr)条件下,已经开发出一种无过渡金属的方法用(杂)芳基底物取代碳硼烷C顶点。这些方法提供的碳硼烷的选择性取代具有合理合成在硼和碳基顶点上均带有取代基的杂官能化硼簇的潜力。

  • Regioselective Insertion of Carborynes into Ethereal C−H Bond: Facile Synthesis of α-Carboranylated Ethers
    作者:Sunewang R. Wang、Zaozao Qiu、Zuowei Xie

    日期:2011.4.20
    Carborynes can exist in two resonance forms, bonding form vs biradical form. The biradical form can be readily generated via the elimination of LiI from 1-iodo-n-lithio-1,n-C(2)B(10)H(10) (n = 2, 7) under UV irradiation. They can undergo α-C-H bond insertion with aliphatic ethers, affording α-carboranylated ethers in excellent regioselectivity at room temperature. This serves as a new methodology for
    碳炔可以两种共振形式存在,键合形式与双自由基形式。通过在紫外线照射下从 1-iodo-n-lithio-1,nC(2)B(10)H(10) (n = 2, 7) 中消除 LiI,可以很容易地生成双自由基形式。它们可以与脂肪族醚进行 α-CH 键插入,从而在室温下以优异的区域选择性提供 α-羰基化醚。这作为产生一系列带有烷氧基单元的官能化碳硼烷的新方法。

    Light-promoted, copper catalyzed cage C–H arylation of o-carboranes with aryl halides has been achieved, leading to the facile synthesis of a variety of 1-aryl-o-carboranes and o-carborane-fused cyclics. This method has the following features: (1) using o-carboranes instead of prefunctionalized iodocarboranes as starting materials; (2) employing earth abundant copper as a catalyst; and (3) room-temperature
