摘　　要：草酸酯加氢是重要的有机化学反应,在工业制乙二醇生产中有着重要的应用.对钌金属配合物均相催化反应的研究进行了综述.以催化反应体系为焦点,探讨了多种因素如温度、氢气压力、催化剂浓度、反应时间、添加剂等对底物转化率以及产物选择性的影响,并讨论了催化反应机理,其中金属-配体协同促进的H2分子异裂,进而完成对底物分子中酯基依次加氢的反应机理是探讨的重点,这为新型催化剂的设计和应用提供参考.Hydrogenation of oxalates is one of the important organic reactions, which has an ultimate use for the industrial production of ethylene glycol. The studies on the ruthenium complexes-based homogeneous catalytic reaction systems are herein summarized. With the focus on the catalytic reaction systems, the important factors with significant influences on the oxalate transformation efficiency as well as the product selectivity are discussed, including temperature, H2 pressure, catalyst concentration, reaction duration, additives, and so on. The catalytic reaction mechanisms are also discussed in detail, where the mechanism for the H2-heterolysis promoted under the metal-ligand cooperation for the oxalate hydrogenation to ethylene glycol is enhanced. This study would be useful for designing the new catalyst applicable in industry.
