“…Oxidation of organic halides to ketones and aldehydes with H 5 IO 6 in ILs is illustrated in Scheme . − Various types of benzylic, allylic, and aliphatic halides can be successfully oxidized to the corresponding ketones and aldehydes in high yields (88–98%) in [C 12 MIM][FeCl 4 ] at 30 °C. However, oxidation of less reactive aliphatic halides needs longer reaction times than other compounds.…”

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.

“…1–3 Traditionally, benzaldehyde is prepared by the chlorination of toluene and subsequent hydrolysis. 4,5 However, the use of chloride in this process contributes to severe equipment corrosion and environmental pollution. In order to meet the requirement of sustainable chemical synthesis, it is urgent to explore effective strategies.…”

N‐Heterocyclic Carbene Catalyzed Ester Synthesis from Organic Halides through Incorporation of Oxygen Atoms from Air

et al. 2020

Oxygenation reactions with molecular oxygen (O 2) as the oxygen source provides a green and straightforward strategy for the construction of O-containing compounds. Demonstrated here is a novel N-heterocyclic carbene (NHC) catalyzed oxidative transformation of simple and readily available organic halides into valuable esters through the incorporation of O-atoms from O 2. Mechanistic studies prove that the deoxy Breslow intermediate generated in situ is oxidized to a Breslow intermediate for further transformation by this oxidative protocol. This method broadens the field of NHC catalysis and promotes oxygenation reactions with O 2. Scheme 1. Dioxygen activation and esterification strategies.
