摘要

二氯化锰（II）和二氯化镍（II）与亚胺吡啶基配体反应，合成了几种新型锰镍配合物，它们在亚胺氮原子上的取代基性质不同。所有配合物都通过分析和红外数据进行了表征，其中一些得到了单晶，并通过x射线衍射确定了它们的分子结构。该配合物与甲基铝氧烷（MAO）结合用于1,3-丁二烯的聚合，得到活性和选择性催化剂，在锰催化剂中主要产生1,2聚丁二烯，在镍催化剂中只产生顺式-1,4聚丁二烯。

Iminopyridine Manganese and Nickel Complexes: Synthesis, Characterization and Behavior in the Polymerization of 1,3-Butadiene

Some novel manganese and nickel complexes were synthesized by reacting manganese(II) dichloride and nickel(II) dichloride with pyridyl-imine ligands differing in the nature of the substituents at the imino nitrogen atom. All the complexes were characterized by analytical and infrared data: for some of them single crystals were obtained, and their molecular structure was determined by X-ray diffraction. The complexes were used in association with methylaluminoxane (MAO) for the polymerization of 1,3-butadiene obtaining active and selective catalysts giving predominantly 1,2 polybutadiene in case of manganese catalysts and exclusively cis-1,4 polybutadiene in case of nickel catalysts.

期刊介绍： Chinese Journal of Polymer Science (CJPS) is a monthly journal published in English and sponsored by the Chinese Chemical Society and the Institute of Chemistry, Chinese Academy of Sciences. CJPS is edited by a distinguished Editorial Board headed by Professor Qi-Feng Zhou and supported by an International Advisory Board in which many famous active polymer scientists all over the world are included. The journal was first published in 1983 under the title Polymer Communications and has the current name since 1985. CJPS is a peer-reviewed journal dedicated to the timely publication of original research ideas and results in the field of polymer science. The issues may carry regular papers, rapid communications and notes as well as feature articles. As a leading polymer journal in China published in English, CJPS reflects the new achievements obtained in various laboratories of China, CJPS also includes papers submitted by scientists of different countries and regions outside of China, reflecting the international nature of the journal.
