Abstract Co, Fe, Ni and Cu complexes of MgO‐supported polysilazane were prepared and found to be able to catalyze the aerobic epoxidation of long‐chain olefins to give corresponding epoxy‐alkanes in the presence of an aldehyde (as reductant) under mild conditions. When the Co complex catalyst was used for the aerobic oxidation of 1‐octene to give 1,2‐epoxy‐hexane, the yield and selectivity could achieve 92% and 100% respectively at 70 °C and under 1‐atm of O 2 . The catalyst was very stable, and could be reused several times without any appreciable change in catalytic activity. Copyright © 1999 John Wiley & Sons, Ltd.
