超分子双膦配体是一类新兴起的基于非共价键作用构筑的双膦配体,近年来引起人们的重视.与传统的共价键连接的双膦配体相比,利用非共价相互作用的可逆性和选择性,超分子双膦配体具有合成简便,组合灵活,易于合成超分子配体库,并利用组合化学的方法对催化体系进行优化和筛选等优点.详细综述了近几年发展的基于氢键、配位键、主客体作用和静电作用等弱相互作用的超分子双膦配体,重点讨论了它们的构建方法以及在不对称催化反应中的应用,并对其发展前景进行了展望.
Supramolecular biphosphine ligands are a new class of bisphosphine ligands constructed on the basis of non-covalent bonds and have drawn more and more attention in recent years.Compared with the traditional covalently linked bisphosphine ligands, The reversibility and selectivity of the valence interaction, the advantages of the supramolecular biphosphine ligands, such as simple synthesis, flexible combination and easy synthesis of supramolecular ligand libraries, and the optimization and screening of the catalytic system by combinatorial chemistry are summarized in detail In recent years, the development of supramolecular bisphosphine ligands based on weak interactions such as hydrogen bonding, coordination bond, host-guest interaction and electrostatic interaction are discussed. Their construction methods and application in asymmetric catalysis are also discussed Its development prospects are forecasted.
