中文摘要译为译为英文摘要时有些错误，希望各位大虾有空的迅速帮忙改一下，下午急用，谢谢。 中文摘要 环戊二烯基过渡金属化合物类在金属有机化学的发展中起着至关重要的作用，钼钨配合物由于其在催化化学、生物化学以及材料科学等诸多方面的应用而引起人们的注意，含二硫型的钼钨配合物特别是它们的合成、结构和谱学分析及其性质测定将仍然是人们研究的热点。为此，我们开展了对含环戊二烯基二硫型的钼钨配合物的合成及性质研究。 1. 本论文共设计合成了48个化合物，其中47个是未知化合物。除对化合物作了红外，核磁，元素分析等测定及分析，还测定了其中6个化合物的晶体结构。 2. 综合考虑配体及空间效应对含环戊二烯基金属化合物的催化效果的影响，基于苯环特殊的立体效应以及电子效应，本论文选定三苯基环戊二烯基作为母体，设计合成了含四氢糠基取代的三苯基环戊二烯和2-苯氧基乙基取代的三苯基环戊二烯共2个含杂原子侧链的配体和含三甘醇基取代的三苯基环戊二烯。通过仲胺跟二硫化碳反应，生成含硫硫单键化合物的方法，设计合成了含吗啉硫硫键以及含双吡啶硫硫键的2种含硫硫单键的化合物。 3. 通过Fe2(SO4)3/醋酸的水溶液与η5-含取代基的三苯基环戊二烯基三羰基钼(钨)的钠盐的相互作用，让其发生氧化偶联反应的方法，制得7个未见报道的含取代环戊二烯基的钼钼、钨钨金属单键化合物，反应产率都可以达到90%以上。 4. 分为四个系列，设计合成了35个未见报道的钼、钨金属配合物：三苯基环戊二烯基的钼钼单键与含硫硫单键的配体反应，得到5个含钼硫单键的配合物；含四氢糠基取代的三苯基环戊二烯基的钼钼、钨钨单键分别与含硫硫单键的配体反应，分别得到5个钼硫配合物和5个钨硫配合物；含2-苯氧基乙基取代的三苯基环戊二烯基的钼钼、钨钨单键分别与含硫硫单键的配体反应，分别得到5个钼硫配合物和5个钨硫配合物；含三甘醇基桥联的三苯基环戊二烯基的钼钼、钨钨单键分别与含硫硫单键的配体反应，分别得到5个钼硫配合物和5个钨硫配合物。 关键词：环戊二烯，钼配合物，钨配合物，X-ray衍射 Cyclopentadienyl type of transition metal compounds in the development of metal organic chemical plays a vital role, molybdenum tungsten complexes in catalysis because of their chemistry, biochemistry and materials science and many other applications and attracted the attention of molybdenum with tungsten disulfide-based complexes in particular their synthesis, structure and spectroscopic analysis and determined the nature of research is that people will still be hot. So, we carried out with cyclopentadienyl molybdenum tungsten disulfide-based Synthesis and Characterization of. 1. In this paper forty eight compounds have been reported, in which forty seven of them are unknown compounds. In addition to using IR, 1HNMR, 13CNMR and EA were characterized by their means, but also by single crystal X-ray diffraction method for the determination of which six a representative of Crystal Structure. 2. Ligands considered and the spatial effect of cyclopentadiene with the catalytic metal compounds the effects of benzene-based three-dimensional special effects and electronic effects, this paper selected triphenyltin cyclopentadiene base as a mother, design and synthesis of tetrahydro-bran containing three phenyl-substituted cyclopentadienyl and 2-phenoxy-ethyl triphenyl substituted cyclopentadienyl contains a total of two side-chain ligand atoms and TEG containing three phenyl-substituted cyclopentadiene. Through the method of secondary amines react with carbon disulfide to produce sulfur sulfur single compounds, design and synthesis of sulfur sulfur single compounds containing morpholine and pyridine with sulfur sulfur single compounds. 2. The adoption of Fe2(SO4)3/acetic acid aqueous solution with η5-containing triphenyl substituent three cyclopentadienyl carbonyl molybdenum (tungsten) the interaction of sodium, so that occurrence of oxidative coupling reaction of its approach, seven no reported triphenyl substituted cyclopentadienyl for the molybdenum molybdenum and tungsten tungsten metal-metal single compound were synthesized, and the reaction yield could reach 90%. 3. Design and Synthesis of the 35 not reported molybdenum, tungsten metal complexes, are divided into four series: Triphenyltin cyclopentadienyl molybdenum molybdenum single bond with the sulfur sulfur single compounds synthesis of five molybdenum sulfur complexes; tetrahydro bran containing three phenyl-substituted cyclopentadienyl molybdenum molybdenum, and tungsten tungsten single bond, respectively, with the sulfur sulfur single compounds synthesis of five molybdenum sulfur complexes and five tungsten sulfur complexes; 2 -phenoxy-ethyl triphenyl substituted cyclopentadienyl molybdenum molybdenum, and tungsten tungsten single bond, respectively, with the sulfur sulfur single compounds synthesis of five molybdenum sulfur complexes and five tungsten sulfur complexes;containing TEG-based triphenyltin bridged cyclopentadienyl molybdenum molybdenum, and tungsten tungsten single bond, respectively, with the sulfur sulfur single compounds synthesis of five molybdenum sulfur complexes and five tungsten sulfur complexes.

Cyclopentadienyl-based transition-metal compounds plays a vital role in the development of metallicl organic chemistry. Molybdenum-tungsten complexes attracts much attention due to their prominent applications in many fields, e.g., catalysis chemistry, biochemistry and materials science. It can be expected that the synthesis, structural and spectroscopic analysis and measurements of properties in disulfide-typed molybdenum-tungsten complexes will yet be a hot theme in the furure. Therefore, the synthesis and properties of cyclopentadienyl-based as well as disulfide-typed molybdenum-tungsten complexes were investigated in the present study. 修改了第一段，感觉问题还不少。剩下的工作由其他虫友来支持吧，太累人了。 |
