copper-catalyzed chemoselective oxidative O-aroylation of 2-acetylphenols, alkyl salicylates and 1,3-dicarbonyl compounds with a wide range of styrene derivatives are described. This approach provides an efficient chemoselective preparation of phenol, alkyl salicylate and enol esters in good to excellent yields. This method represents an alternative protocol for the classical esterification reactions.
Toluene oxidation is one of the substantial industrial technologies since oxidized products are industrially very important intermediates. A Fe3O4@cysteine@Cu‐catalysed reaction that uses tert‐butyl hydroperoxide as oxidant to produce esters from toluene and β‐diketones or β‐keto esters, enolate precursors, has been developed. Oxidativeesterification of toluene with 1,3‐dicarbonyl derivatives led
甲苯氧化是重要的工业技术之一,因为氧化产物是工业上非常重要的中间体。已经开发出一种Fe 3 O 4 @胱氨酸@Cu催化的反应,该反应使用叔丁基氢过氧化物作为氧化剂,由甲苯和β-二酮或β-酮酸酯(烯醇盐前体)生成酯。甲苯与1,3-二羰基衍生物的氧化酯化反应导致C-O键形成和直接的CH-H功能化。
