  Pt（II）介导的末端烯烃与过氧化氢的“绿色”催化环氧化中的区域选择性和非对映选择性：对特殊底物选择性的机理洞察

  摘要：

  由于严格的空间和电子要求，最近开发的具有“绿色”氧化剂 35% 过氧化氢的缺电子 Pt(II) 催化剂 1 在末端烯烃的环氧化中显示出高活性和完全的底物选择性。在带有末端和内部双键的孤立二烯的存在下，环氧化对于末端环氧化物的产生是完全区域选择性的。通过反应进程动力学分析方法可以深入了解该机制，该方法强调了 1 在限速步骤中激活烯烃和 H2O2 的特殊作用，提供了 H2O2 对烯烃进行亲核氧化的罕见例子。

• Modified ethylene-vinyl alcohol copolymer and method for the production thereof
  申请人：——

  公开号：US20040096683A1

  公开（公告）日：2004-05-20

  Provided is a modified ethylene-vinyl alcohol copolymer (C) having an ethylen content of 5 to 55 mol %, which contains a specific structural unit (I) in an amount of 0.3 to 40 mol % and may be obtained by reacting an ethylene-vinyl alcohol copolymer (A) with a monofunctional epoxy compound (B) having a molecular weight of not more than 500. This can be produced by a method for producing the modified ethylene-vinyl alcohol copolymer (C) which comprises melting and kneading an ethylene-vinyl alcohol copolymer (A) with a monofunctional epoxy compound (B) in an extruder. The modified ethylene-vinyl alcohol copolymer (C) is superior to a unmodified ethylene-vinyl alcohol copolymer (A) in transparency, stretchability, flexibility and flexing resistance due to the specific structural unit (I) incorporated therein, and thus, can be used as a barrier material in various applications requiring the above performance capabilities.
