Title
Efficient oxidation of cyclohexene over tetrakis(diperoxomolybdo) phosphate immobilized on poly(phthalazinone ether sulfone ketone) with hydrogen peroxide
Abstract

Heteropoly anion [PMo4O24]3− (PMo) was immobilized on the quaternary-ammonium poly(phthalazinone ether sulfone ketone) (QAPPESK) support by taking advantage of the overall negative charge of anion. The supported catalyst QAPPESK–PMo was fully characterized by FT-IR and XRD. The results of analyses indicated that the PMos were finely dispersed on the polymer support via chemical interactions. This supported catalyst was employed to catalyze oxidation of olefins with hydrogen peroxide, and satisfying results were obtained under mild heterogeneous conditions. The effects of various reaction factors, such as solvent, the amount of H2O2 and catalyst used, were studied. Furthermore, the leaching and recycling tests revealed that the supported catalyst was highly efficient and robust.

Graphical abstractIn this work, the heteropoly anion [PMo4O24]3− (b) with crystal structure was immobilized on the amorphous quaternary-ammonium poly(phthalazinone ether sulfone ketone) (a), and the XRD pattern of the supported catalyst (c) revealed that the anions immobilized on the polymer were not in a crystal state but in an amorphous state, and [PMo4O24]3− species were highly dispersed as fine particles on the polymer support.Figure optionsDownload full-size imageDownload as PowerPoint slide
