The coordinatively saturated vanadium MIL-47 as a low leaching heterogeneous catalyst in the oxidation of cyclohexene

► V-MIL-47 can be a selective catalyst in the epoxidation of cyclohexene. ► Water should be avoided as the solvent for the peroxide. ► Leaching is negligible and the structural integrity of the MOF is preserved. ► Computational studies show the necessity of breaking of two V-terephthalic bonds. ► Two competitive cyclohexene epoxidation pathways are discussed.
