  Effects of Molecular Geometry on the STM Image Contrast of Methyl- and Bromo-Substituted Alkanes and Alkanols on Graphite

  摘要：

  Scanning tunneling microscopy (STM) images have been collected for a series of substituted alkanes and alkanols that form ordered overlayers at room temperature on highly ordered pyrolytic graphite surfaces. Molecules that have been imaged possess an internal bromide, with or without terminal alcohol groups (HO(CH2)(9)CHBr(CH2)(10)OH and H3C(CH2)(16)CHBr(CH2)(16)CH3), an internal -OH group (H3C(CH2)(16)CHOH(CH2)(16)CH3), and an internal methyl group (H3C(CH2)(16)CHCH3(CH2)(16)CH3). These data allow comparison to the STM image contrast reported previously for molecules in which -OH, -Br, and -CH3 groups were located in terminal positions of alkane chains adsorbed onto graphite surfaces. When the functional groups were in gauche positions relative to the alkyl chain, and thus produced molecular features that protruded toward the tip, the functional groups were observed to produce bright regions in a constant current STM image, regardless of the STM contrast behavior observed for these same functional groups when they were in terminal positions of adsorbed alkyl chains. These observations are in excellent agreement with theoretical predictions of the STM behavior of such systems. Additionally, several interesting packing structures have been observed that have yielded insight into the intermolecular forces that control the packing displayed by these overlayers.

  路易斯酸改性的介孔氧化铝：甲基三氧杂ium在带有官能团的烯烃复分解中的新型催化剂载体

  摘要：

  发现路易斯酸改性的介孔氧化铝是烯烃复分解反应中的有效载体以及甲基三氧or（MeReO 3）的活化剂。特别是MeReO 3掺杂在氯化锌改性的介孔氧化铝上的催化剂在温和条件下催化了具有官能团（如乙酰氧基，烷氧基羰基，酰基，氯和溴基）的烯烃的复分解。这种新型的非均相催化体系不仅促进了这种官能化烯烃的复分解，而且促进了在强固体酸上经常遇到的没有双键迁移的简单烯烃的复分解反应。我们在这里提出了一种在易位反应中用路易斯酸性中孔材料活化金属配合物的新方法。从环境和经济的有机合成的观点来看，这种新颖的非均相催化剂将优于常规催化剂。

• Metathesis of unsaturated fatty acids: Synthesis of long-chain unsaturated-α,ω-dicarboxylic acids

  AbstractThe self‐metathesis of readily available monounsaturated FA has the potential of being an important pathway for the synthesis of symmetrical long‐chain unsaturated‐α,ω‐dicarboxylic acids (C18−C26). Previous studies on the self‐metathesis of monounsaturated FA esters using ruthenium catalysts in solution, however, suffered from low conversions as a result of the thermodynamic control of the reaction. We have found that the second‐generation Grubbs catalyst can effectively catalyze the solvent‐free self‐metathesis of monounsaturated FA of varying purity (from 90 to 99%) to afford two important products—monounsaturated dicarboxylic acids and hydrocarbons—in very high molar conversions (>80%). This solvent‐free self‐metathesis reaction also works for monounsaturated FA containing additional functional groups. Reactions were conducted at catalyst loadings as low as 0.005 mol%, and turnover numbers as high as 10,800 could be obtained. This discovery represents an attractive approach to the large‐scale production of useful monounsaturated‐α,ω‐dicarboxylic acids and long‐chain unsaturated hydrocarbons by means of this solvent‐free ruthenium‐catalyzed self‐metathesis of readily available monounsaturated FA.

  chloride-modified mesoporous alumina catalyzed the metathesis of olefins with functional groups such as acetoxy, alkoxycarbonyl, acyl, chlorine, and bromine groups under mild conditions. The novel heterogeneous catalytic system promoted the metathesis of not only such functionalized olefins but also simple olefins without double bond migration that was often encountered on strong solid acids. We here present a new
