“…4 , but with the addition of the oxidant (aq. H 2 O 2 ), only one phase was observed, which maybe due to the formation of peroxometalate complex [33]. Under the optimized conditions (Scheme 5), it was possible to oxidize biphenyl carbinol to benzophenone in 96% yield, and recycle the catalytic system for at least five cycles.…”

“…Initially sodium tungstate and sodium molybdate were tested as catalyst, using [bmim]BF 4 as solvent, although only 34% and 40% yield, respectively, were achieved. The authors explained this result by the low solubility of the inorganic salts in the IL, and also the known effect of ammonium salts to affect the catalytic activity of these salts [33]. In order to increase the reaction efficiency, the authors developed a new catalyst where sodium was replaced by another cation.…”

Ionic liquids (ILs) have attracted the scientific community due to several advantages compared with traditional solvents such as their low volatility and high ability to dissolve different organic and inorganic compounds, among other advantages. Transition metals can be toxic compounds; however, this issue can be minimized when used in catalytic amounts which also allows reaction efficiency and selectivity increases. The combination of metal catalysis with the use of ILs can be a powerful tool for several organic reactions, taking advantage of the most attractive property of the ILs, which is the possibility of an easier recycling of the catalytic system, increasing the greenness of the process. The application of ILs in metal-catalyzed oxidation reactions of alcohols and sulfides is discussed in this chapter.

Ionic Liquids in Selective Oxidation: Catalysts and Solvents

Selective oxidation has an important role in environmental and green chemistry (e.g., oxidative desulfurization of fuels and oxidative removal of mercury) as well as chemicals and intermediates chemistry to obtain high-value-added special products (e.g., organic sulfoxides and sulfones, aldehydes, ketones, carboxylic acids, epoxides, esters, and lactones). Due to their unique physical properties such as the nonvolatility, thermal stability, nonexplosion, high polarity, and temperature-dependent miscibility with water, ionic liquids (ILs) have attracted considerable attention as reaction solvents and media for selective oxidations and are considered as green alternatives to volatile organic solvents. Moreover, for easy separation and recyclable utilization, IL catalysts have attracted unprecedented attention as "biphasic catalyst" or "immobilized catalyst" by immobilizing metal- or nonmetal-containing ILs onto mineral or polymer supports to combine the unique properties of ILs (chemical and thermal stability, capacity for extraction of polar substrates and reaction products) with the extended surface of the supports. This review highlights the most recent outcomes on ILs in several important typical oxidation reactions. The contents are arranged in the series of oxidation of sulfides, oxidation of alcohols, epoxidation of alkenes, Baeyer-Villiger oxidation reaction, oxidation of alkanes, and oxidation of other compounds step by step involving ILs as solvents, catalysts, reagents, or their combinations.

An overview of the recent advances in the field of polyoxometalate, ionic liquid hybrids, is proposed with a special attention paid to their application in catalysis, more precisely biphasic and heterogeneous catalysis. Both components of the hybrids are separately outlined pointing to their useful properties and potential for catalysis, followed by the description of the hybrids preparation and synergy between components in a large range of organic transformations. And finally a vision on the future developments is proposed.
