Liquid-Phase Selective Oxidation of Methane to Methane Oxygenates

Catalysts, Год журнала: 2024, Номер 14(3), С. 167 - 167

Опубликована: Фев. 24, 2024

Methane is an abundant and relatively clean fossil fuel resource; therefore, its utilization as a chemical feedstock has major impact on the industry. However, inert nature makes direct conversion into value-added products difficult under mild conditions. Compared to gas-phase selective oxidation of methane, there have been several recent advances in liquid-phase methane. This review categorizes reports methane according solvent oxidant used. The advantages disadvantages each approach are discussed. High yields methyl bisulfate methanol precursor can be achieved using SO3 sulfuric acid; however, more attention should paid separation process overall economic analysis. aqueous-phase with situ generated H2O2 quite promising from environmental point view, provided that economical reducing agent Based current state-of-the-art this topic, directions for future research proposed.

Metal‐ and photocatalyst‐free aerobic photoinduced benzyl C(sp3)–H bonds oxidation

Asian Journal of Organic Chemistry, Год журнала: 2024, Номер unknown

Опубликована: Июнь 5, 2024

Abstract Photoinduced the direct oxidation of benzyl C( sp 3 )−H bonds provides an attractive strategy for producing high‐value chemicals or intermediates. Unlike conventional approaches that typically require transition‐metal catalysts, semiconductors, and organic photosensitizers as photocatalysts, herein we report a bromine salt‐promoted photoinduced aerobic protocol methylarenes. By applying NH 4 Br both radical source hydrogen atom transfer agent, methylarenes to corresponding carboxylic products exhibits high conversion selectivity. Furthermore, control experiments confirm reactive oxygen species are proved be essential success this transformation. This metal‐/strong oxidant‐/photocatalyst‐free paradigm deep
