Abstract

With the rapid development of “green” chemistry; researchers are highly interested towards more sustainable approaches and prefer to choose eco-friendly synthetic routes and materials. This paper deals with the development of a novel reusable heterogeneous palladium catalyst for Heck reaction. The catalyst (mPAN-Pd) was developed by a simple procedure via synthetic modification of polyacrylonitrile (PAN) with monoethanolamine (MEA) followed by complexation with palladium chloride (PdCl₂). After detailed characteristic studies, the catalytic efficiency of mPAN-Pd in Heck coupling reaction was systematically evaluated and optimised the reaction condition through a set of experiments. This heterogeneous catalytic system was found be applicable over a series of aryl halides and terminal alkenes leading to corresponding coupling products in good yields. Furthermore, this catalyst offers easy recyclability by simple filtration and reused for at least 5 cycles of Heck reaction without losing much of its activity.

一种新型可重复使用的聚合物负载钯催化剂用于Heck反应

随着“绿色”化学的迅速发展；研究人员对更可持续的方法非常感兴趣，更喜欢选择环保的合成路线和材料。本文研究了一种可重复使用的多相钯Heck反应催化剂的研制。用单乙醇胺（MEA）对聚丙烯腈（PAN）进行改性，再与氯化钯（PdCl2）络合，制备了mPAN-Pd催化剂。通过详细的特性研究，系统评价了mPAN-Pd在Heck偶联反应中的催化效率，并通过一系列实验对反应条件进行了优化。发现该非均相催化体系适用于一系列芳基卤化物和末端烯烃，可得到相应的偶联产物，产率较高。此外，该催化剂易于回收，通过简单的过滤和重复使用至少5个循环的Heck反应，而不会失去太多的活性。

期刊介绍： The Journal of Organometallic Chemistry targets original papers dealing with theoretical aspects, structural chemistry, synthesis, physical and chemical properties (including reaction mechanisms), and practical applications of organometallic compounds. Organometallic compounds are defined as compounds that contain metal - carbon bonds. The term metal includes all alkali and alkaline earth metals, all transition metals and the lanthanides and actinides in the Periodic Table. Metalloids including the elements in Group 13 and the heavier members of the Groups 14 - 16 are also included. The term chemistry includes syntheses, characterizations and reaction chemistry of all such compounds. Research reports based on use of organometallic complexes in bioorganometallic chemistry, medicine, material sciences, homogeneous catalysis and energy conversion are also welcome. The scope of the journal has been enlarged to encompass important research on organometallic complexes in bioorganometallic chemistry and material sciences, and of heavier main group elements in organometallic chemistry. The journal also publishes review articles, short communications and notes.
