Synthesis of 1,2-epoxycyclopentane and/or 1,2-cyclopentanediol by oxidation of cyclopentene with aqueous solution of hydrogen peroxide

Highly Efficient Epoxidation of Cyclopentene Catalyzed by Magnetically Recoverable Mg-doped Cobalt Ferrites with Greatly Improved Performances

“…Chemical transformations by heterogeneous catalysis are more attractive compared to homogenous catalysis, due to the ease of catalyst recovery [4] . A large number of tungsten-based heterogeneous catalysts, such as supported WO 3 [1,5] , H 3 PMo 12 À n W n O 40 ·xH 2 O [3] , phosphotungstic quaternary ammonium salt [6] and phosphotungstic acid encapsulated in metal-organic framework UiO-66 [7] have been used in the oxidation of cyclopentene to produce glutaraldehyde. On the other hand, to our best knowledge, only little attention has been paid for epoxidation of cyclopentene.…”

“…Consequently, the transformation of cyclopentene into more valuable derivatives is of interest. Selective oxidation is the most appropriate route to produce valuable derivatives, such as cyclopentene oxide, cyclopentenone, cyclopentanone and glutaraldehyde, which have important practical applications for production of macromolecular compounds, plasticizers, fragrances, pharmaceuticals, bactericides and agricultural chemicals . Of the cyclopentene derivatives, cyclopentene oxide is an important intermediate in organic synthesis …”
