• Ethics and Foreign Policy: The Antinomies of New Labour's ‘Third Way’ in Sub-Saharan Africa
  作者：Rita Abrahamsen、Paul Williams

  DOI：10.1111/1467-9248.00312

  日期：2001.6

  This article explores how New Labour has attempted to implement its ideas about a ‘third way’ foreign policy in sub-Saharan Africa. Through an examination of British foreign policy practices, we explore whether New Labour has succeeded in finding a ‘third way’ between traditional views of socialism and capitalism in Africa. In particular, the article focuses on New Labour's attempts to build peace, prosperity and democracy on the African continent. We conclude that although New Labour's claims to add an ‘ethical dimension’ to foreign policy have succeeded in giving Britain a higher profile in the international arena, the implementation of such a policy is intrinsically difficult. These difficulties in turn arise from the antinomies embodied in New Labour's policy, or more specifically from the tension between the liberal internationalism of the third way and traditional concerns for the national interest, as well as the contradictions inherent in a commitment to both political and economic liberalism.

  这篇文章探讨了新工党如何试图在撒哈拉以南非洲实施其关于“第三条道路”外交政策的想法。通过对英国外交政策实践的审查，我们探讨新工党是否成功地在非洲传统社会主义和资本主义观念之间找到了一种“第三条道路”。特别是，文章关注新工党在非洲大陆上建立和平、繁荣和民主的努力。我们得出结论，尽管新工党声称在外交政策中增加了“道德维度”成功地使英国在国际舞台上更加引人注目，但这种政策的实施本质上是困难的。这些困难反过来源于新工党政策所体现的矛盾，更具体地说，源于第三条道路的自由国际主义与对国家利益的传统关注之间的紧张关系，以及对政治和经济自由主义的承诺中固有的矛盾。
• Some uses of mischmetall in organic synthesis

  Mischmetall, an alloy of the light lanthanides, has been used in a variety of organic reactions, either as a coreductant in samarium(II)-mediated reactions (Barbier and Grignard-type reactions, pinacolic coupling reactions) or as the promoter of Reformatsky-type reactions. It has been also employed as the starting material for easy syntheses of lanthanide trihalides, the reactivity of which has been

  cleavage of unfunctionalized secondary (2°) and tertiary alcohols (3°) is essential for valorization of macromolecules and biopolymers. We developed a blue-light-driven iron catalysis for aerobic oxidation of 2° and 3° alcohols to acids via α-C–C bond cleavages at room temperature. The first example of oxygenation of the simple tertiary alcohols was reported. The iron catalyst and blue light play critical

  未官能化的仲醇（2°）和叔醇（3°）的选择性α-CC键断裂对于大分子和生物聚合物的增值至关重要。我们开发了一种蓝光驱动的铁催化剂，用于在室温下通过α-CC键断裂将2°和3°醇有氧氧化为酸。报道了简单叔醇氧化的第一个例子。铁催化剂和蓝光起着至关重要的作用，可以使醇类形成高反应性的O自由基，并随后发生两次α-CC键断裂。

  Grignard-type additions were readily achieved under the mediation of CuI (10 mol%) and samarium (2 equiv.) by employing various organohalides, e.g. benzyl, aryl, heterocyclic and aliphatic halides (Cl, Br or I), and diverse carbonyl compounds (e.g. carbonic esters, carboxylic esters, acid anhydrides, acyl chlorides, ketones, aldehydes, propylene epoxides and formamides) to afford alcohols, ketones

  通过使用各种有机卤化物，例如苄基、芳基、杂环和脂肪族卤化物（Cl、Br 或 I）以及各种羰基化合物，在 CuI（10 mol%）和钐（2 当量）的介导下很容易实现格氏型加成（例如碳酸酯、羧酸酯、酸酐、酰氯、酮、醛、环氧丙烷和甲酰胺）分别以高效率和化学选择性提供醇、酮和醛，其中可能涉及有机钐中间体。

In addition, organocerium and -lanthanum reagents have been obtained from samarium diiodide catalysed reactions between organic halides and cerium or lanthanum metal, giving a new route to organolanthanoid compounds.

  Barbier 和 Grignard 型烯丙基化和苄基化是通过使用催化量的二碘化钐和作为助还原剂的混合稀土（一种轻镧系元素的合金）实现的。提出了合理的催化方案。此外，通过二碘化钐催化有机卤化物与铈或镧金属的反应获得有机铈和镧试剂，为有机镧系化合物提供了一条新途径。铈和镧的三价苄基和烯丙基有机金属化合物似乎比相应的钐更稳定。(© Wiley-VCH Verlag GmbH, 69451 Weinheim, Germany, 2002)
