![عکس صفحه اول مقاله: Simple preparation of some reusable and efficient polymer-supported tungsten carbonyl catalysts and clean epoxidation of cis-cyclooctene in the presence of H2O2 Simple preparation of some reusable and efficient polymer-supported tungsten carbonyl catalysts and clean epoxidation of cis-cyclooctene in the presence of H2O2](/preview/png/68574.png)
Tungsten hexacarbonyl was immobilized onto polystyrene (2% cross-linked with divinylbenzene) via different linkages to afford polymer-supported tungsten carbonyl catalysts. These catalysts were used for the epoxidation of cis-cyclooctene with hydrogen peroxide. The effect of different solvents and oxygen donors were investigated in the epoxidation of cis-cyclooctene with catalyst 2e and CH3CN was chosen as reaction media and H2O2 as oxidant. We found that the polymer-supported tungsten carbonyl catalysts were efficient and reusable catalysts in this reaction. These catalysts could be reused 3–10 times in the epoxidation of cis-cyclooctene.
Efficient oxidation of cyclooctene with H2O2 catalyzed by supported tungsten carbonyl catalysts is reported. Figure optionsDownload as PowerPoint slide
