摘要：

Four camphyl beta-diketone iron(III) complexes were synthesized and used in the asymmetric epoxidation of styrene analogues affording the corresponding epoxides in good chemical yields and enantioselectivities in the range of 47.5%similar to 91.6% ee with combined use of molecular oxygen and 2-ethylbutyraldehyde as sacrificial aldehyde at 25 similar to 30 degrees C. Some factors influencing yield and enantioselectivity were discussed.
