  摘要：

  制备了一种新的基态有机电子给体，其在双吡啶亚烷基骨架上具有四个强烈的π-供电子亚氨基膦酸酯取代基。循环伏安法显示，该对夫妇涉及中性有机供体及其指示，相对于饱和甘汞电极（SCE），记录的氧化还原电势为-1.70V。可以通过涉及易于制备的吡啶鎓离子前体的去质子化反应来分离（44％）这种高还原性有机化合物，或者更方便地就地生成。该给体能够还原各种芳基卤化物，并且由于其氧化还原电位，被发现是第一个对热诱导的N，N还原SN键裂解有效的有机给体。-二烷基磺酰胺和丙二醛的还原性加氢脱氰作用。

  Accelerated Biphasic Hydroformylation by Vesicle Formation of Amphiphilic Diphosphines

  摘要：

  The synthesis, aggregation behavior, and catalytic activity of rhodium complexes of a series of Xantphos derivatives with surface-active pendant groups, -4-C6H4O(CH2)(n)C6H4(SO3Na)- (n = 0, 3, 6) is described. Electron microscopy experiments show that these ligands and their complexes form vesicles in water if the hydrophobic part of the ligand is large enough (n = 3, 6). The formed aggregates are stable at elevated temperatures (90 degrees C), and their presence lends to a significant enhancement of the solubility of organic substrates in aqueous solution. This enhanced solubility results directly in a higher reaction rate in the rhodium-catalyzed hydroformylation of 1-octene. Furthermore, recycling experiments show that the TOF and the high selectivity toward the more valuable linear aldehyde remains approximately the same in four consecutive runs. This indicates that the aggregates stay intact during the recycling and the active rhodium complex is retained in the water-phase quantitatively.

• Base‐Mediated O‐Arylation of Alcohols and Phenols by Triarylsulfonium Triflates

  A mild and efficient protocol for O-arylation of alcohols and phenols (ROH) by triarylsulfonium triflates was developed under transition-metal-free conditions. Various alcohols, including primary, secondary and tertiary, and phenols bearing either electron-donating or electron-withdrawing groups on the aryl rings were smoothly converted to form the corresponding aromatic ethers in moderate to excellent

  Direct cross-dehydrogenative coupling of different inert C−H bonds is the most straightforward and environmentally benign method to construct C−C bonds. In this paper, we developed an iron-catalyzed intramolecular cross-dehydrogenative arylation (CDA) between benzylic C(sp3)H bond and aromatic C(sp2)H bond. From the readily available linear substrates, 1-arylnaphthalenes and 4-arylcoumarins can be

  Structure-activity relationship of sphingosine-1-phosphate receptor agonist was examined. In terms of reducing the flexibility of molecule, hit compound 1 was modified to improve S1P(1) agonistic activity as well as selectivity over S1P(3) agonistic activity. Novel S1P agonists with cinnamyl scaffold or 1,2,5,6-tetrahydropyridine scaffold were identified. (C) 2011 Elsevier Ltd. All rights reserved.
