  无溶剂氯化铁 (III) 催化的酯直接酰胺化

  摘要：

  酰胺官能团在具有多种有益应用的广泛有机化合物中很突出。在这项工作中，我们报告了通过氯化铁 (iii) 催化的酯直接酰胺化合成这些官能团。该反应在无溶剂条件下进行，发现与一系列胺和酯底物相容，可在较短的反应时间内生成所需的酰胺，并且在 15 mol% 的催化剂负载量下产率良好至极好。

  The present disclosure relates to a solid catalyst for propylene polymerization and a process for manufacture of a propylene polymer or copolymer using the solid catalyst, and provides a solid catalyst including carriers produced via a reaction between dialkoxy magnesium and metal halide, titanium halide, an organic electron donor, etc. and a process of manufacture of a propylene-based block copolymer via copolymerization of propylene-α-olefin using the solid catalyst. Particularly, internal electron donors including an ester group and an alkoxy group are used as two kinds of organic electron donors used in the present disclosure, and, thus, a block copolymer having high activity and excellent stereoregularity and a high rubber content via copolymerization with α-olefin can be produced using a solid catalyst system suggested in the present disclosure.

  本公开涉及一种用于丙烯聚合的固体催化剂以及使用该固体催化剂制造丙烯聚合物或共聚物的工艺，并提供了一种固体催化剂，包括通过二烷氧基镁与金属卤化物、卤化钛、有机电子供体等反应生成的载体，以及使用该固体催化剂通过丙烯-α-烯烃的共聚制造丙烯基嵌段共聚物的工艺。 特别是，本公开中使用了包括酯基和烷氧基在内的内部电子供体作为两种有机电子供体，因此，使用本公开中建议的固体催化剂体系，通过与α-烯烃共聚，可以生产出具有高活性和优异立体规整性以及高橡胶含量的嵌段共聚物。
