【摘要】 金属有机化学是融合有机化学与无机化学的一门交叉学科,发展最为活跃、迅速、富有生命力,是当代化学的前沿领域之一。伴随绿色化学的兴起,合成一类无毒、无污染的多功能配合物成为当今金属有机化学的一个研究热点。正是基于以上研究背景,本论文设计并合成了一系列新型的金属有机化合物,以期用于丙交酯的开环聚合得到良好的催化效果。主要内容分为以下三章:第一章为导论,介绍了本论文工作的研究背景,分为三部分:(1)胍基金属有机化合物的研究进展;(2)β-二亚胺金属有机化合物的性质、合成与催化应用;(3)丙交酯开环聚合合成聚乳酸的研究进展,包括对催化剂类型,催化机理,催化效果等方面的分析与探索。第二章分别以芳香胺(邻苯二胺、间苯二胺、对苯二胺)和脂肪胺(乙二胺)为例,探讨了胍基配体及其金属有机化合物的合成方法,并且对一意外得到的极为对称的脒基锂盐进行了反应机理研究,最后利用NMR、元素分析、X-Ray单晶衍射仪和熔点测定仪等各种技术手段对所得化合物的结构、性质进行分析表征。第三章简单介绍了β-二亚胺类金属有机化合物的研究进展,并且以文献中报道的最经典的β-二亚胺化合物为原料合成了一系列β-二亚胺配体及其金属有机化合物,最后利用NMR、元素分析、X-Ray单晶衍射仪和熔点测定仪等各种技术手段对所得化合物的结构、性质进行分析表征。最后对本论文所有工作的得失进行了回顾与总结,同时提出了我们未来工作的具体计划,希望我们在不断的努力中获得更有效的成果。更多还原

【Abstract】 Organometallic chemistry is a cross-science of organic chemistry and inorganic chemistry and one of the important branches in the modern chemistry, which is developing most actively, promptly and full of vitality. With the rising of green chemistry, synthesis of nontoxic and noncontaminative organometallic compounds as new materials or catalysts has become a hot topic of organometallic chemistry.Based on the background of the above research, we designed and synthedized a series of new organometallic complexes to seek the excellent catalysts for the ring-opening polymerization (ROP) of lactide. The details are listed as follws:Chapter 1.The background of the research work was introduced. It was divided into three sections: (1) The progress of guanidinato-metal complexes; (2) The progress ofβ-diimido-metal complexes in organic synthesis, catalysis and properties; (3) Progress of ring-opening polymerization (ROP) of lactide, including synthesis and reaction mechanisms.Chapter 2. Synthesis of guanidinato ligands and their metallic complexes was discussed and their structural characterizations were studied by NMR, elemental analysis and X-ray diffraction analysis.Chapter 3. The progress ofβ-diketiminato organometallic compounds were introduced and a series ofβ-diketiminato ligands and their metal complexes were synthedized and characterized.更多还原
