Chiral Schiff Base Complexe Catalyst for the Asymmetric Epoxidation

The study on synthesis of the chiral Schiff base transition metal complexes and their catalytic performance has attracted more attentions due to their applications in the asymmetric epoxidation of olefins. This article summarises some recent results on the chiral Schiff base transition metal complexes and their catalytic applications in the asymmetric epoxidation of olefins, including the synthesis and the activities of several novel Schiff base transition metal complexes. Catalytic mechanism and perspective of the chiral Schiff base transition metal complexes including their predominance and disadvantages are also discussed.
