• Nonenzymatic Kinetic Resolution of 3-Hydroxyalkanamides with Chiral Copper Catalyst
  作者：Osamu Onomura、Yosuke Demizu、Yuki Kubo、Yoshihiro Matsumura

  DOI：10.1055/s-2008-1032057

  日期：2008.2

  Kinetic resolution of 3-hydroxyalkanamides with good to high selectivities was achieved by benzoylation using copper(II) triflate and (R,R)-PhBox [2,2′-isopropylidenebis(4-phenyl-2-oxazoline)] as catalyst, which also mediated enantioselective tosylation of 2,2-bis(hydroxymethyl)alkanamides with high efficiency.

  使用三酸铜（II）和 (R,R)-PhBox [2,2′-异亚丙基双（4-苯基-2-恶唑啉）] 作为催化剂，通过苯甲酰化作用实现了 3-羟基烷酰胺的动力学解析，并具有良好至高的选择性。

  A solid catalyst component for olefin polymerization includes a solid component obtained by causing a magnesium compound(a), a titanium halide compound(b), and an electron donor compound(c) to come in contact with each other, the titanium compound in an amount equivalent to a titanium content of 0.2 to 2.5 wt% in the solid catalyst component being washed away from the solid catalyst component by washing with heptane. A granular or spherical polymer that has high stereoregularity and a narrow particle size distribution can be obtained in high yield while suppressing production of a fine powder by polymerizing an olefin using a catalyst that includes the solid catalyst component.

  用于烯烃聚合的固体催化剂组分包括通过使镁化合物(a)、卤化钛化合物(b)和电子供体化合物(c)相互接触而得到的固体组分，钛化合物的量相当于固体催化剂组分中 0.2 至 2.5 wt%的钛含量，通过庚烷洗涤从固体催化剂组分中洗掉。使用包含固体催化剂组分的催化剂聚合烯烃，可以获得立体粒度高、粒度分布窄的颗粒状或球状聚合物，同时抑制细粉末的产生。
