Superparamagnetic CuCl nanoparticles were prepared and identified as an effective heterogeneous catalyst for the tandem transformation of methylarenes and 1,3‐dicarbonyl compounds into the corresponding enole esters by the use of tert‐butyl hydroperoxide as an external oxidant. The catalyst can be removed from the reaction medium simply by use of an external magnet. As a consequence, various derivatives
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。

Synthesis of enol carbamates was achieved via nickel‐catalyzed oxidative coupling of formamides with 1,3‐dicarbonyl compounds in the presence of tert‐butyl hydroperoxide at 40 °C. Various derivatives of enol carbamates were synthesized by this method in good to excellent yields.
