摘 要

二茂铁是金属有机化合物的典型代表，特有的夹心结构使其具有芳香性、亲脂性、稳定性、低毒性及单电子氧化还原的可逆性，一直是科学工作者研究的一个热点。

金属配合物因其新颖、独特的结构，在光学、电学、磁学、催化化学方面都有潜在的应用，且近年来在催化材料方向的研究也逐渐成为新的热点，其中含亚铜（d10）的簇合物，在实验和理论研究上均已取得一定进展。二茂铁很容易进行取代反应，并且作为单电子氧化还原中心，二茂铁又可以在多数溶液中经过多次可逆的单电子氧化还原反应，是一种理想的氧化还原修饰基团。本小组近年来一直致力于研究将具有电化学活性的二茂铁与具有特殊性质的基团相结合,得到同时具有多种理化性质的超分子物质。 基于软硬酸碱规则（HSAB）原理，软酸趋向于跟软碱形成稳定的配合物。迄今为止，对亚铜配合物的研究多以O、N等硬路易斯碱为配位原子，属于软碱的碲元素与软酸Cu 结合相关研究较少。我们要将Te原子引入含二茂铁基团的配体中，以期待获得更加稳定基于二茂铁碲醚的亚铜配合物并研究其性质。 本课题设计合成基于二茂铁碲醚的亚铜配合物，对其中间物及产物进行化学表征，确定组成和结构及探讨其催化性质。

关键词：二茂铁 碲醚 亚铜 配合物

Abstract

Ferrocene is a kind of metal organic complex, with a sandwich structure, the special structure of ferrocene has the aromaticity, lipotropy, stability, low toxicity and oxidation-reduction reversibility, so the ferrocene and its derivatives has been a hot topic in the research of the scientific workers.

Metal coordination compounds because of its unique structure, in the optical, electrical, magnetic, catalytic chemistry aspects have potential applications and in recent years in the direction of the catalytic materials research has gradually become a new hot spot, which contains clusters of cuprous (D10) complexes, in experimental and theoretical studies have achieved certain progress. Ferrocene is easy to substitution reaction, and as a single electron oxidation reduction center, ferrocene and in most of the solution after several reversible one electron oxidation reduction reaction is a kind of ideal redox groups. The group in recent years has been working on with electrochemical activity of Ferrocene and combined with the special nature of the group, also has a variety of physical and chemical properties of supramolecular compounds. Rule (HSAB) based on HSAB principle, soft acids tend to form stable complexes with soft base. So far, study on the matching of cuprous multi with O, N and other hard Lewis bases as coordination atoms, belonging to the soft base of tellurium and soft acid Cu binding related research is less. We want to te atoms introduced containing ferrocene ligands and to look forward to obtain more stable based on ferrocenyl tellurides of cuprous complexes and study their properties. This topic design and synthesis based on ferrocenyl tellurides cuprous complexes and of intermediates and products of chemical characterization and determine the composition and structure and investigate its catalytic properties.

Key words: ferrocene telluriether cuprous composition
