    Novel p-block metallacarboranes with 4,1,10-SnC2B10 and 4,1,12-SnC2B10 architectures are described; the structures of bipyridyl adducts of these compounds reveal very different bipyridyl orientations yielding unique experimental information on the relative trans influences of facial B and C atoms in the cage.

    Reduction of 1,12-closo-C2B10H12 or its C,C-dimethyl analogue with sodium in liquid ammonia followed by metallation with CpCo}2+, (arene)Ru}2+ or (dppe)Ni}2+ fragments affords the first examples of 4,1,10-MC2B10 species; thermolysis of these yields the appropriate 4,1,12-MC2B10 isomers, unavailable for (arene)Ru metallacarboranes by similar thermolysis of known 4,1,6-MC2B10 compounds.
    在液中,用还原1,12-闭合-C2B10H12或其C,C-二甲基类似物,随后与CpCo}2+、(arene)Ru}2+或(dppe)Ni}2+片段进行属化反应,首次合成了4,1,10-MC2B10物种;热解这些化合物可以得到相应的4,1,12-MC2B10异构体,这些异构体无法通过已知的4,1,6-MC2B10化合物的类似热解反应得到,也不适用于(arene)Ru属碳硼烷

    Reduction of the tethered carborane 1,2-μ-(CH2SiMe2CH2)-1,2-closo-C2B10H10 followed by metallation with CpCo} or (p-cymene)Ru} fragments affords both C,C′-dimethyl 4,1,2-MC2B10 and 4,1,6-MC2B10 species. DFT calculations indicate that the barriers to isomerisation of both 4-Cp-4,1,2-closo-CoC2B10H12 and 4-(η-C6H6)-4,1,2-closo-RuC2B10H12 to their respective 4,1,6-isomers are too high for this to be the origin of the unexpected formation of 4,1,6-MC2B10 products (in marked contrast to the related isomerisation of 1,2-closo-C2B11H13 to 1,6-closo-C2B11H13), and, indeed, the 4,1,2-species are recovered unchanged from refluxing toluene. Equally, the DFT-calculated profile for the isomerisation of [7,8-nido-C2B10H12]2− to [7,9-nido-C2B10H12]2− suggests that the unexpected formation of 4,1,6-metallacarboranes is unlikely to result from isomerisation of a reduced (nido) carborane following desilylation. Instead, the source of the 4,1,6-MC2B10 compounds is traced to desilylation of 1,2-μ-(CH2SiMe2CH2)-1,2-closo-C2B10H10 by Li or Na prior to reduction. The supraicosahedral metallacarboranes 1,8-Me2-4-Cp-4,1,8-closo-CoC2B10H10, 1,12-Me2-4-Cp-4,1,12-closo-CoC2B10H10 and 1,12-Me2-4-(p-cymene)-4,1,12-closo-RuC2B10H10 are also reported with all new species characterised both spectroscopically and crystallographically.
    通过对联结的卡巴烯1,2-μ-(CH2SiMe2CH2)-1,2-closo-C2B10H10进行还原,然后用CpCo}或(p-cymene)Ru}片段进行属化,可以得到C,C′-二甲基4,1,2-MC2B10和4,1,6-MC2B10物种。DFT计算表明,4-Cp-4,1,2-closo-CoC2B10H12和4-(η-C6H6)-4,1,2-closo-RuC2B10H12转变为各自的4,1,6-同分异构体的能量障碍过高,因此这并不是4,1,6-MC2B10产品意外生成的原因(与1,2-closo-C2B11H13转变为1,6-closo-C2B11H13 的相关同分异构化形成明显对比),实际上,4,1,2-物种在回流甲苯中保持不变。同样,DFT计算的[7,8-nido-C2B10H12]2−到[7,9-nido-C2B10H12]2−的同分异构化的能量轮廓也表明,4,1,6-属卡巴烯的意外形成不太可能是由于在去化后还原的(nido)卡巴烯所导致的。相反,4,1,6-MC2B10化合物的来源追溯到在还原之前,Li或Na对1,2-μ-(CH2SiMe2CH2)-1,2-closo-C2B10H10进行去化。此外,还报道了超二十面体属卡巴烯1,8-Me2-4-Cp-4,1,8-closo-CoC2B10H10、1,12-Me2-4-Cp-4,1,12-closo-CoC2B10H10和1,12-Me2-4-(p-cymene)-4,1,12-closo-RuC2B10H10,所有新物种均通过光谱学和晶体学进行了表征。
