  摘要：

  从商业上可获得的材料以有效的方式合成了两个系列的BN菲，包括母体化合物。两种亲本BN菲在溶液中都是强荧光的。它们的吸收和发射光谱在很大程度上取决于BN的位置和方向。此外，两个系列的BN菲对亲电试剂的反应性完全不同，并且这些物种可以通过交叉偶联反应进一步官能化。

• Recyclable Selective Palladium-Catalyzed Synthesis of Five-, Six- or Seven-Membered Ring Lactones and Lactams by Cyclocarbonylation in Ionic Liquids
  作者：Fangguo Ye、Howard Alper

  DOI：10.1002/adsc.200606100

  日期：2006.9

  ionic liquids, BMIM PF6 or BMIM NTf2, are used successfully for the palladium-catalyzed cyclocarbonylation of 2-allylphenols and anilines, 2-vinylphenols, and 2-aminostyrenes. The reaction proceeds cleanly and efficiently to afford high yields of lactones or lactams with good or excellent selectivity for one isomer. The ionic liquid containing the palladium catalyst, and ligand, is recyclable in all cases

  离子液体BMIM PF 6或BMIM NTf 2已成功用于2-烯丙基苯酚和苯胺，2-乙烯基苯酚和2-氨基苯乙烯的钯催化环羰基化。反应干净，有效地进行，以高产率获得内酯或内酰胺，并且对一种异构体具有良好或优异的选择性。包含钯催化剂和配体的离子液体在所有情况下都是可回收的。

  has been synthesized in only three steps (76% overall yield) from easily accessible 1-bromo-2-vinylnaphthalene, along with several substituted derivatives. The reactivity of these previously unknown BN-aromatic compounds toward organolithium compounds and bromine has been studied. This latter reaction affords bromo-substituted compounds that are suitable for further functionalization via Suzuki and Sonogashira

  A grease composition is produced by mixing a thickener of a calcium sulfonate complex and a second thickener component (polyurea, a metallic soap, a complex metallic soap or an N-substituted terephthalamic acid metal salt) into a base oil. This grease composition is excellent in heat resistance, load carrying capacity, water resistance and lubricating life. Moreover, a grease composition is produced by mixing a thickener of an N-substituted terephthalamic acid metal salt and a second thickener component (polyurea, a metallic soap or a complex metallic soap) into a base oil. This grease composition is excellent in heat resistance, oxidation stability and lubricating life. Furthermore, a grease composition is produced by mixing a thickener of 10 to 90% by mass of polyurea and 90 to 10% by mass of a complex metallic soap into an ester oil having a kinematic viscosity at 40° C. of 20 to 180 mm 2 /s. This grease composition generates only a few dusts even at a high temperature and has excellent high-temperature performance. Still further, a grease composition is produced by mixing a thickener of 10 to 90% by mass of polyurea and 90 to 10% by mass of a complex metallic soap into a base oil having a kinematic viscosity at 40° C. of 50 to 500 mm 2 /s. This grease composition has excellent performance under a high-speed and high-temperature environment and provides a rolling apparatus with excellent seizuring life.
