Salen-Mn(Ⅲ)配合物与卟啉铁的结构和性质相似,其在不对称催化反应中具有高对映异构选择性。重点介绍了Salen-Mn(Ⅲ)的配体合成方法、其催化环氧化反应的机理,并对影响催化不对称环氧化反应因素进行了详细阐述。将Salen-Mn(Ⅲ)固载到固体载体上,催化剂分子充分分离,避免形成片μ-oxo-Mn(Ⅵ)二聚体,从而保持催化剂的活性,并易于回收均相催化剂固载化技术的应用,有力地推动了金属Salen-Mn(Ⅲ)配合物应用研究的发展。
The structure of Salen-Mn (Ⅲ) complex is similar to the structure and properties of porphyrin iron, which has high enantioselectivity in the asymmetric catalytic reaction. The ligand synthesis method of Salen-Mn (Ⅲ) is introduced emphatically, which catalyzes the mechanism of epoxidation reaction and elaborates on the factors affecting the asymmetric epoxidation. Salen-Mn (III) is immobilized on a solid support, and the catalyst molecules are sufficiently separated to avoid the formation of a sheet of μ-oxo-Mn (Ⅵ) dimer so as to maintain the activity of the catalyst and to be easily recovered. Homogeneous catalyst immobilization technology Application, effectively promoted the application of metal Salen-Mn (Ⅲ) complex research and development.
