| 中文摘要: |
| 催化活性物种的结构演变广泛存在于过渡金属催化反应中。由于金的强亲金相互作用和亲碳性,在金催化体系中往往存在单核、双核、高核有机金物种之间的结构转变,并对催化机制产生重要影响。本文介绍了不同形态金催化剂的常见催化机理,综述了催化反应原位偕双金物种和有机金簇合物的结构演化行为及其对应于自身结构所产生的独特催化作用,提出了未来对明确真实催化活性物种结构及其与底物作用方式两方面的研究想法,也为其它过渡金属催化体系中此类结构演化研究提供了新视角。 |
| 英文摘要: |
| The structural evolution of catalytically active species is widely observed in transition metal-catalyzed reactions. Due to strong aurophilic interaction and carbophilicity of gold, structural transformations among mononuclear, dinuclear, and polynuclear organogold species are often detected in gold-catalyzed systems, which have significant implications for the catalytic mechanisms. This paper presents the common catalytic mechanisms of gold catalysts in different forms, reviews the in situ structural evolution of gem-diaurated species and organogold clusters during catalytic reactions, and highlights their unique catalytic functions corresponding to their respective structures. In addition, ideas for future research on clarifying both the structure of real catalytically active species and their catalytic mode of interaction with organic substrates are proposed, providing a novel perspective for the study of such structural evolution in other transition metal-catalyzed systems. |
