  摘要：

  1，1-二芳基乙烯与四氯化碲的反应可生成二聚体以及包含两个与TeCl 2结合的乙烯分子的加合物。测量了加合物的uv，ir，nmr和质谱，并研究了温度和溶剂变化对nmr光谱的影响。提出并讨论了几种可能的结构。加合物（Ph 2 C CH 2）2 TeCl 2中的氯原子（IIa）可以交换为其他卤素原子。已经研究了加合物的各种反应，其中一些碲原子保留在一个σ键结合的双-（2,2-二芳基乙烯基）碲化物产品中，而另一些则丢失，从而生成衍生自1,1-的产物。仅二芳基乙烯部分。

  Reactions of trimethylsilyl-derived iodohydrins of the type R1R2CH–CH(I)OTMS, with electron-rich olefins, and the effects of certain factors on these reactions, were studied. The trimethylsilyl-derived iodohydrins were obtained in situ by reacting R1R2CH–CHO (R1 = R2 = H; R1 = H, R2 = alkyl, phenyl) with TMSI. The corresponding trimethylsilyl enol ether derivatives (R1R2CCH–OTMS), and 1,1-diarylethylenes were the olefins used. Aldehydes of the type RCH2–CHO reacted smoothly in the presence of TMSI to yield the condensation product RCH2–CHC(R)–CHO. Both RCH(–CHCAr2)2 and the cyclic acetal 5 were obtained as main products of the RCHO–TMSI–CH2CAr2 reaction system, depending on the [RCHO] ∶ [TMSI] ∶ [CH2CAr2] concentration ratio. The mechanisms of formation for the various main products and by-products are discussed. TMSI substitutes, formed by reacting Me3SiCl with each of several Lewis acids, were also used.

  研究了从三甲硅基衍生的碘醇R1R2CH-CH(I)OTMS与富电子烯烃的反应，以及某些因素对这些反应的影响。三甲硅基衍生的碘醇是通过R1R2CH-CHO(R1=R2=H;R1=H，R2=烷基、苯基)与TMSI反应在原位获得的。所用的烯烃是相应的三甲硅基烯醇醚衍生物(R1R2CCH-OTMS)和1，1-二芳基乙烯。在TMSI存在下，RCH2-CHO类型的醛顺利反应生成缩合产物RCH2-CHC(R)-CHO。RCHO-TMSI-CH2CAr2反应体系主要生成RCH(-CHCAr2)2和环状缩醛5，这取决于[RCHO]：[TMSI]：[CH2CAr2]的浓度比。讨论了各种主要产物和副产物的形成机理。还使用了通过Me3SiCl与几种Lewis酸反应形成的三甲硅基取代物。
• Ethics and Foreign Policy: The Antinomies of New Labour's ‘Third Way’ in Sub-Saharan Africa
  作者：Rita Abrahamsen、Paul Williams

  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。

  spectra of DPE samples adsorbed on HY and Hß zeolites indicate that the spin population of these samples is too low (<1015 spin · g−1) to contain significant amounts of any paramagnetic species. In addition, IR spectra of the organic material incorporated within HY and Hß is very similar to those of some DPE dimers. Product studies after solid-liquid extraction of zeolites and silica-alumina in which DPE

  The interaction of resonance-stabilized carbanions with methyl radicals produced by the irradiation of the carbanions in dimethyl sulfoxide is governed by the pK/sub a/ of the carbanion conjugate acid to a greater extent than by the stability of the resulting radical anion. This kinetic effect is explained using energetic considerations based on the Hammond postulate and is further rationalized by

  共振稳定的碳负离子与由碳负离子在二甲亚砜中辐照产生的甲基自由基的相互作用在更大程度上受碳负离子共轭酸的 pK/sub a/ 控制，而不是受所得自由基阴离子的稳定性控制。使用基于哈蒙德假设的能量考虑来解释这种动力学效应，并通过分子轨道相关图进一步合理化。
