IBN介导的芳香烯烃环氧化反应研究

Olefins, with an unsaturated C = C double bond in the molecular structure, can take epoxidation reaction and product corresponding epoxides, which are important intermediates in organic synthesis. As a kind of green oxidants, olefins epoxidation with molecular oxygen is an important approach. According to the reported literatures, the addition of metal ions and large amount of reducing agent is necessary in oxygen epoxidation reaction system, a more simple and efficient oxidation method is to be studied. In this paper, an AIBN mediated olefin epoxidation reaction was obtained, with molecular oxygen as oxidant, azo radical initiator AIBN as mediator, 1,2-dichloroethane as solvent, react for 16 h at 80 ℃. Experimental result was excellent and the epoxides yield was up to 82%.
