Ionic compounds containing the polyoxomolybdate anion [Mo6O19](2-) and [(n-C4H9)(4)P](+) (tetra-butylphosphonium), [(n-C4H9)(3)P(n-C14H29)](+) (tributyl (tetradecyl)phosphonium), [Dbmim](+) (1-butyl-3-methylimidazolium) and [Dbmim] (1,2-dimethyl-3-butylimidazolium) cations were prepared and characterized, including the determination of three of the solid state structures by single-crystal X-ray diffraction. These compounds were applied as catalysts for the epoxidation of olefins with urea hydrogen peroxide (UHP) as oxidant in the ionic liquid [Bmim]PF6. Additionally, the oxidation of sulfides to sulfoxides with hydrogen peroxide (H2O2) in several solvents was investigated. The polyoxomolybdate catalysts showed a good performance for epoxydation of olefins as well as for oxidation of sulfides. Furthermore, the catalysts can be recycled several times in oxidation reactions. We present this methodology for the oxidation reaction in a simple, economically, technically, and environmentally benign manner.     «
