Synthesis and Characterization of Task-Specific Ionic Liquids Based on Peroxydisulfate and Their Application in Oxidation Reactions

Four new task‐specific ionic liquids based on the peroxydisulfate ion were synthesized by the ion exchange method and characterized by FTIR and 1H NMR spectroscopy and elemental analysis. The physicochemical characteristics of these ionic liquids such as density, thermal stability, conductivity, viscosity, and solubility in common solvents have been investigated in detail. The experimental results testify that the ionic liquids prepared show excellent performance as both oxidant and medium in given oxidation reactions of alcohols and thiols under mild reaction conditions. Four task‐specific ionic liquids based on peroxydisulfate anions were synthesized and characterized. These ionic liquids have the desired properties for given oxidation reactions of alcohols and thiols, and they show excellent performance as both oxidant and medium in solvent‐ and catalyst‐free reaction systems.
