ABSTRACT

Over the last few years, many Schiff base complexes of metal ions have exhibited substantial catalytic activity in various reactions such as oxidation, Henry reaction, hydroxylation, aldol condensation, and epoxidation. The literature survey shows that, over the past few years, there have been few reports on the catalytic aldol and Henry reaction where Schiff base-based metal complexes act as homogeneous or heterogeneous catalysis. This review reorganizes the various transition metal Schiff base complexes as well as chiral Schiff base metal complexes, which have potential application in catalytic activity on aldol and Henry reaction. Schiff bases are an important class of chelating ligands due to its coordination tendency and their complexes exhibit a wide range of applications in various fields like anti-bacterial, anti-fungal, antiviral, anti-cancer, antioxidant, anti-inflammatory, magnetism, luminescence, conductivity, sensing, catalytic, and so on. This review mainly focuses on the catalytic activities of Schiff base ligands and their transition metal complexes to the aldol and Henry reaction.

摘要

近年来，许多金属离子席夫碱配合物在氧化、亨利反应、羟基化、羟醛缩合和环氧化等各种反应中表现出显着的催化活性。文献调查表明，近年来，关于席夫碱基金属配合物作为均相或多相催化的羟醛和亨利反应的报道很少。本综述重组了各种过渡金属席夫碱配合物以及手性席夫碱金属配合物，这些配合物在羟醛和亨利反应的催化活性方面具有潜在的应用。席夫碱因其配位倾向而成为一类重要的螯合配体，其配合物在抗菌、抗真菌、抗病毒、抗癌、抗氧化、抗炎、磁性、发光、导电、传感、催化等。本综述主要关注席夫碱配体及其过渡金属配合物对羟醛和亨利反应的催化活性。
