This project aims to design a series of 8-hydroxyquinoline manganese complexes by synthesizing different ligands, and systematically study their catalytic activity and selectivity in the epoxidation reaction of olefins. The synthesized complexes were characterized by UV-visible spectroscopy, nuclear magnetic resonance, infrared spectroscopy and other techniques, and the reaction products were analyzed by gas chromatography to explore the catalytic effect of different olefins in the epoxidation reaction. The results show that different ligands have different effects on catalytic activity, and 8-hydroxyquinoline manganese complexes can efficiently and selectively catalyze the epoxidation reaction of olefins.【Keywords】 Molecular switch; 8-hydroxyquinoline manganese complex; Epoxidation of olefins; Catalytic activity; Selectivity
