With the supported "clayniac" catalyst, in the presence of i- butyraldehyde as a sacrificial reducer, olefins are epoxidized in good yields by compressed air at room temperature, in a convenient procedure.
Green oxidation of alkenes in ionic liquid solvent by hydrogen peroxide over high performance Fe(III) Schiff base complexes immobilized on MCM-41

, p. 801 - 805 (2014)
A series of Fe(III) Schiff base complexes immobilized on MCM-41 were prepared and characterized by various physicochemical and spectroscopic methods. The complexes were used for oxidation of cyclohexene by 30% hydrogen peroxide in the presence and absence of ethylmethyl imidazolium chloride (EMIM) ionic liquid as solvent. The immobilized complexes proved to be effective catalysts and generally exhibited much higher catalytic performance than their homogeneous analogue. Catalytic performance of the complexes was also found to be closely related to the Schiff base ligands used. Additionally, ion liquid solvent efficiently improved all the catalytic performances. Finally, the reaction was extended to different alkenes using the heterogeneous complex 2-L4. Among all the alkenes, those containing π-electron-withdrawing groups and trans-orientations exhibited lower tendency for oxidation.

Page/Page column 6, (2008/06/13)
An improved catalytic process for the preparation of epoxides from alkenes using a combination of transition metal salt, an inorganic promoter and an organic additive in absence of solvent or in the presence of a solvent with commercially available hydrogen per oxide has been disclosed. Thus, styrene oxide was prepared at a kilogram scale in 86% isolated yield with purity >95%.
