Environmentally benign aerial oxidation of benzoin over copper containing hydrotalcite

Synthesis of α,β‐Diketotriazoles by Aerobic Copper‐Catalyzed Oxygenation with Triazole as an Intramolecular Assisting Group

“…Moghaddam et al have reported the aerobic oxidation of aryl thioacetamides into the corresponding α-keto aryl thioamides in good yields with copper(II) chloride as a catalyst. 1,2-Diketones have also been prepared by the oxidation of α-hydroxy ketones with copper as, for example, copper-containing hydrotalcite [12] or the "copper(II)/cesium carbonate system" [13] in aerobic conditions. Zhang et al have reported the synthesis of 1,2-diketones from 1,3-diketones with FeCl 3 as the catalyst and tert-butyl nitrite as the oxidant.…”

Thermodynamically Stable Pickering Emulsion Configured with Carbon-Nanotube-Bridged Nanosheet-Shaped Layered Double Hydroxide for Selective Oxidation of Benzyl Alcohol

“…Layered double hydroxide (LDHs) as typical 2D nanosheet-shaped materials has been conceived to be promising candidates as basic supports for the oxidation of alcohol reaction because of their tunable composition and environmental friendliness. − It was also found that the emulsion stabilized by LDHs can be produced via emulsification; nevertheless, the emulsion is unstable due to their low attachment energy . As a result, the poor stability of emulsion stabilized by LDHs limits the practical application of LDHs in emulsion catalysis reactions to a certain degree.…”

An Efficient Oxidation of Benzoins to Benzils by Manganese(II) Schiff Base Complexes Using Green Oxidant

“…Benzil, an alpha diketone, is one of the important organic intermediates and has received an enormous attention because of its practical applications in organic and pharmaceutical industry such as photosensitive and synthetic reagents [1][2][3]. e oxidation of benzoins is one of the most efficient and practical methods for the synthesis of benzils.…”
