This catalytic system containing polyoxometalates and H2O2 has applied the most succesful system in obtaining epoxide product with excellent yields for cis-cyclooctene in acetonitrile at 55 & DEG;C. Maximum epoxidation efficiency of 99 % was observed under optimized conditions for Ph4P[Cp*MoW5O18] (2c).EnglishOLEFIN EPOXIDATIONMOLYBDENUM(VI) COMPLEXESTUNGSTEN COMPLEXESCRYSTAL-STRUCTUREMODERIVATIVESPROGRESSArticle
