  Tax-Aided Financial Services Companies and the Cost of Capital

  摘要：

  AbstractOver the past two decades, the governments of several European countries have implemented special tax devices to attract the finance centres of multinational companies. This paper determines how the cost of capital for investments made by multinationals is affected by the tax regimes, bringing into play the Irish financial services company, the Belgian co‐ordination centre, the Dutch finance company and the Luxemburg company coupled with a Swiss finance branch. It gives evidence that intermediation of a tax‐aided services company in the financing scheme of a foreign subsidiary provides an important tax saving. However, the home and source countries' tax regimes influence the hierarchy of the less heavily taxed treasury and finance centres. The methodology relies on the marginal effective tax rates theory and consists of an extension of Alworth's (1988) model to include treasury centres.

  Oxidative Coupling of Alkylated Anisole Derivatives Using MoCl₅

  摘要：

  尽管五氯化钼（MoCl5）具有路易斯酸特性，但它可以用于烷基化茴香醚衍生物的选择性氧化偶联反应，而不会发生底物的转烷基化或去叔丁基化。靠近供体功能的空间需求似乎是有利的。

• Homocoupling of Aryl Halides Using Nickel(II) Complex and Zinc in the Presence of Et₄NI. An Efficient Method for the Synthesis of Biaryls and Bipyridines

  Reduction of NiX2(PPh3)2 with zinc in the presence of Et4NI gives a nickel catalyst which has been proven to be useful for the coupling of aryl halides. This nickel catalyst can be prepared in THF without an additional triphenylphosphine and is effective for the homocoupling of aryl chlorides, bromides, and iodides to produce biaryls and bipyridines in good yields. The reported new approach provides a simple access to novel derivatives of biaryls and bipyridines.

  在乙基四氟铵存在下，用锌还原NiX2(PPh3)2可以得到一种镍催化剂，该催化剂已被证明对芳基卤化物的偶联反应非常有效。此镍催化剂可以在THF中制备，无需额外的三苯基磷，并且对芳基氯、溴和碘的同类偶联反应有效，以良好的产率生成双芳烃和双吡啶。所报道的新方法提供了一种简单的方法，用于获得双芳烃和双吡啶的新型衍生物。

  Treatment of bis(aryl)tellurium dichlorides or diaryl tellurides with degassed Raney nickel readily affords the corresponding biaryls. The bis(aryl)tellurium dichlorides were prepared from TeCl4 and the appropriate aromatics, with or without a Lewis acid as a catalyst, depending on the reactivity of the aromatic. The diaryl tellurides were prepared by reduction of the dichlorides with hydrazine. Attempts

  用脱气的阮内镍处理双（芳基）二氯化碲或二芳基碲化物容易得到相应的联芳基。取决于芳族化合物的反应性，在有或没有路易斯酸作为催化剂的情况下，由TeCl 4和适当的芳族化合物制得二氯化双（芳基）碲。通过用肼还原二氯化物来制备二芳基碲化物。尝试制备不对称的二氯化物经常导致交换反应（RTeCl 3 + R'H→R'TeCl 3 + RH）。
