  摘要：

  乙基间三甲基苯与二氯甲烷中的发烟硝酸在-50°C下反应，生成单硝基乙基间三甲基苯、3,5-二甲基-4-乙基硝基苯、2-硝基-3,5-二甲基-4-乙基硝基苯和二硝基乙基三甲基环己烯酮，而与混合酸硝化时，主要产物是单硝基和二硝基衍生物，以及少量2-硝基和2,6-二硝基-3,5-二甲基-4-乙基硝基苯、二苯基甲烷和未鉴定的硝基羰基化合物，可能是硝基苯甲醛。正丙基间三甲基苯硝化后得到类似结果。如果通过加入大量过量的硝化剂对碳氢化合物进行硝化，反应后不久主要产物是2,6-二硝基-3,5-二甲基-4-烷基硝基苯，或者当混合物在室温下放置时，主要产物是2,6-二硝基-3,5-二甲基-4-烷基苯甲醛。史密斯和基斯通过乙基间三甲基苯硝化得到的硝基化合物在123°C熔化，被描述为三硝基-4-乙基邻二甲苯，被确定为2,6-二硝

• Efficient Synthesis of Sterically Hindered Arenes Bearing Acyclic Secondary Alkyl Groups by Suzuki-Miyaura Cross-Couplings

  Bulky P,PO ligands were designed to inhibit isomerization and reduction side reactions during the cross coupling between sterically hindered aryl halides and alkylboronic acids. Suzuki–Miyaura cross‐couplings between di‐ortho‐substituted aryl bromides and acyclic secondary alkylboronic acids have been achieved with high yields. The method has also enabled the preparation of ortho‐alkoxy di‐ortho‐substituted

  庞大的P，P = O配体设计用于在位阻芳基卤化物和烷基硼酸之间的交叉偶联过程中抑制异构化和还原副反应。高产率地实现了二邻位取代的芳基溴化物和无环仲烷基硼酸之间的Suzuki-Miyaura交叉偶联。该方法还能够以优异的收率制备带有异丙基的邻烷氧基双邻取代芳烃。合成方法的实用性已在雌酮的后期修饰中以及在向棉酚的新合成途径中的应用中得到了证明。

  The acid catalysed dienol-benzene rearrangement of methyl substituted o- and p-propargylcyclohexadienols (18–22, 34 and 35) was investigated. In the first step water is eliminated to yield the corresponding methyl propargyl benzonium ions (cf. scheme 6, a), which undergo [1s, 2s] sigmatropic rearrangements to give propargylbenzenes (28, 29, 30, 38) and [3s, 4s] sigmatropic rearrangements to give allenylbenzenes

• Nest materials and some chemical characteristics of nests of a New World swarm-founding polistine wasp,<i>Polybia paulista</i>(Hymenoptera Vespidae)

  Nest material, nitrogen and amino acid composition of nests Were examined in a New World swarm-founding polistine wasp, Polybia paulista. This wasp used minute vegetable chips, Which Were a dominant material, plant hairs, and mud and/or inorganic particles as nest building materials. A SEM observation and nitrogen and amino acid contents indicated that the amount of oral secretion used for construction and maintenance of the nests was quite small, compared With that used in Polistes nests. Such a small amount of oral secretion used for nest building is considered to be associated with their social organization (division of labor) and nest material. This study hypothesized that the amounts of oral secretion used for nest building are determined by an interaction among social organization, nest material and environmental factors, such as precipitation.Twenty-four amino acids were detected from protein in the nests of P. paulista, of which serine, glycine, alanine, valine, proline, aspartic acid and glutamic acid were major components. Amino acid composition of the protein in the nests of P. paulista differed distinctly from those of other so far known polistine and vespine wasps. The present result supports the view that amino acid composition of the protein in nests reflects phylogenetical relationships among wasps.
