中文摘要: 本项目旨在发展新型的含金属离子液体,并研究其性质和协同催化性能。提出两种新的策略来合成对空气和水稳定的含金属离子液体:1)通过调节过渡金属离子、配体数目以及抗衡离子,来合成金属中心存在于阳离子中的离子液体;2)利用配体的化学转化来获得含多种配体的离子液体。而后考察其特殊的物理化学性质,分析其结构-性质的关系。最后利用含金属离子液体同时具有金属中心和次级相互作用活性位点的特征,将其应用于碳氢官能化反应,通过各种手段来研究其作用机理,从基元反应的角度来理解含金属离子液体。

英文摘要: This program aims at the development of new metal-containing ionic liquids, as well as the research on their properties and cooperative catalysis. Firstly, two strategies will be used to synthesis the metal-containing ionic liquids which are not sensitive to air and steam: 1) various transition metal cations, ligands and counter ions are ajusted to achieve the ionic liquids whose metal exists in the cation; 2) the transformation of ligands can lead to new ionic liquids containing more than one ligand, without the change on the metal centre. Their special physicochemical properties will then be discovered to study the relationship with their structures. The metal-containing ionic liquids possess both the methal centre and the secondary interactions. They are supposed to exhibit catalytic activity in C-H activation. Various methods will be used to study the catalysis mechanism in order to understand the fundamental reactions of metal-containing ionic liquids.
