Dioxygen Affinities and Biomimetic Catalytic Performance ofTransition-metal Complexes with Benzoin Schiff Bases

Department of Chemistry Sichuan University Chengdu 610064

Received Date: 4 May 1999

The oxygenation constants of transition-metal complexes with benzoin Schiff bases were measured and these complexes were first employed as models for mimicking monooxygenase in catalytic epoxidation of styrene. The highest conversion and selectivity were up to 39.6% and 100% respectively at ambient temperature and pressure. The effects of structures of the bridge group R in the ligands on the dioxygen amities and catalytic activities to epoxidize styrene were also investigated.
