  新型细分散钯催化剂在丝素蛋白上的高化学选择性加氢方法：其制备及活性

  摘要：

  通过将丝素蛋白浸入Pd（OAc）2的MeOH溶液中2天（在Ar气氛下）至4天（在空气中），制备钯-丝蛋白复合物（Pd / Fib ）。Pd（OAc）2逐渐被丝蛋白吸收，并在室温下以甲醇作为还原剂快速还原丝蛋白缀合的Pd（OAc）2，成为Pd（0）络合物。在芳族酮和醛，卤化物，N -Cbz保护基和苄基酯的存在下，Pd / Fib催化的乙炔，烯烃和叠氮化物的化学选择性加氢反应很容易使用Pd / C或Pd / C（en）作为催化剂进行氢化。

• Preparation of silk fibroin-supported Pd(0) catalyst for chemoselective hydrogenation: reduction of palladium(II) acetate by methanol on the protein
  作者：Hironao Sajiki、Takashi Ikawa、Hiromi Yamada、Kozo Tsubouchi、Kosaku Hirota

  DOI：10.1016/s0040-4039(02)02472-3

  日期：2003.1

  The Pd/fibroin (Fib) was easily prepared by the auto-reduction of the silk-fibroin conjugated Pd(OAc)2 using MeOH as a solvent and a reductant and exhibited good chemoselectivity in the hydrogenation of olefins and azides in the presence of aromatic carbonyls and/or halogens or an O-benzyl protective group.

  通过使用MeOH作为溶剂和还原剂，将丝素蛋白共轭的Pd（OAc）2自动还原，可以轻松制备Pd /丝素蛋白（Fib），并且在芳烃存在下烯烃和叠氮化物的氢化反应中表现出良好的化学选择性。羰基和/或卤素或O-苄基保护基。
• Process for making allylic esters of tetrabromophthalic acid

  Allylic esters of tetrabromophthalic acid are formed using allylic alcohol both as a reactant and a solvent. In the first step, the alcohol and a base are reacted with tetrabromophthalic anhydride to form the half-ester sodium salt. In the second step, the half-ester sodium salt is reacted with allylic halide to form the diester which crystallizes from solution. The excess solvent may be treated to recover the raw materials or recycled.

  四溴邻苯二甲酸的烯丙基酯是用烯丙基醇作为反应物和溶剂形成的。 第一步，醇和碱与四溴邻苯二甲酸酐反应生成半酯钠盐。 第二步，半酯钠盐与烯丙基卤化物反应生成二酯，二酯从溶液中结晶。 过量的溶剂可通过处理回收原材料或循环使用。

  A resin for lens with a high refractive index prepared by compolymerizing one or more benzenedicarboxylic acid esters substituted by halogen in the nucleus and represented by the formula (I), (wherein X represents CI or Br, n represents 2 or 4, m represents 0 or 1, and R represents H or methyl) with one or more monofunctional monomers having a refractive index of 1.55 or more as homopolymer and being radical-polymerizable, and lens composed of it are disclosed. This resin for preparing lens has a high refractive index and is excellent in workability (such as grindability) and impact resistance. In addition, the monofunctional monomer(s) and the bifunctional monomer(s) are well compatible with each other upon copolymerization, and polymerication distortion difficultly takes place.

  本发明公开了一种具有高折射率的镜片用树脂，其制备方法是将一种或多种核内被卤素取代且由式（I）表示的苯二甲酸酯（其中 X 代表 CI 或 Br，n 代表 2 或 4，m 代表 0 或 1，R 代表 H 或甲基）与一种或多种折射率为 1.55 或以上且可进行自由基聚合的单官能团单体进行均聚，并由其组成镜片。 这种镜片用树脂具有高折射率，且加工性（如研磨性）和抗冲击性优异。 此外，单官能团单体和双官能团单体在共聚时彼此相容性良好，不易发生聚合变形。

  A process for improving the flame retardancy, hygroscopic, soil release and other properties of a polymer substrate is provided in which the substrate is contacted with a suitable aqueous mixture containing a water-soluble monomer and an organic halogen-containing hydrophobic carrier compound at a temperature of between about 40°C to 100°C. Polymerization of the monomer is thereafter initiated by a chemical or physical initiator to form a polymer evenly disposed on the substrate. The flame retardancy, hygroscopic, soil release and other surface properties of the substrate are thereby improved. The mixture may be in the form of an emulsion wherein the hydrophobic carrier compound is emulsified by an appropriate agent. The invention also pertains to the improved substrates prepared in accordance with the present process.
