手性稀土配合物在不对称催化应用中的研究进展

近年来随着光学纯化合物需求的不断增大,不对称催化逐渐成为科学研究的前沿领域之一.稀土元素则是由周期表中ⅢB族Sc、Y和镧系元素(La~Lu)的17种元素组成.相比其他过渡金属与各类配体轨道间的作用,稀土金属有其独特之处,因此,近年来手性稀土配合物在不对称催化领域的应用,也逐渐引起人们的重视.根据各类手性配体中所含配位原子的不同,对手性稀土配合物的类型及相关的不对称催化反应作简要综述.

Research progress of chiral rare earth complexes in asymmetric catalysis

With the increasing demand of the optical compounds,asymmetric catalysis becomes a hot research area.The rare earth elements are defined as the elements of lanthanide from La to Lu,together with Sc and Y.Compared to the orbital interaction between the other transition metals and ligands,the one between rare earth metals and ligands is unique.Therefore,the application of chiral rare earth complexes in asymmetric catalysis has also attracted much attention.This paper reviewed research progress of chiral rare earth complexes in asymmetric catalysis.
