| 摘 要： | 以聚丙烯腈纤维为基体，通过较简单的方法获得了偕胺肟纤维- 钯(II)配合物，采用FTIR、XPS等技术对其结构和性能进行了表征。本研究考察了该配合物在不同反应条件下对碘苯与苯乙烯的Heck反应的催化性能，结果显示：该配合物在较温和的条件下即可很好的催化Heck反应,经重复使用5次后，1，2-二苯乙烯的产率仍达90%以上，并且反应结束后催化剂易于从反应体系中分离。对于其他不同底物之间的Heck反应，偕胺肟纤维- 钯(II)配合物同样显示较好的催化性能。

| Abstract: | Chelating fibers containing amidoxime groups (AOCF) supported palladium complex (AOCF-Pd(II)) was synthesized from Polyacrylonitrile fiber via a simple method. The catalyst was characterized by FTIR, XPS, etc. The catalytic performance for Heck reaction of iodobenzene with styrene was investigated under different reaction conditions. The results show that the catalyst has a high catalytic activity for the Heck reaction. After 5 times repeated use, the yield of 1, 2-stilbene above 90% is still obtained. And the catalyst is easy to isolation after reaction. For the different substrates of Heck reaction, the catalyst also shows great performance. |
