(Pd@PS)-catalysed carbonylative esterification of the hydroxy group of 5-hydroxymethyl furfural (5-HMF) to its corresponding aryl esters has been developed. The use of Pd@PS, oxalic acid as CO source, and aryl halides was first explored for the aryl ester of 5-HMF synthesis. Here, we investigated the vital role of a polystyrene support to avoid the commonly known decarbonylation of 5-HMF. The reaction
已开发出无脱羰基、聚
苯乙烯负载、Pd (Pd@PS) 催化的
5-羟甲基糠醛 (5-
HMF) 羟基羰基化酯化反应生成相应的芳基酯。首次探索了使用 Pd@PS、
草酸作为 CO 源和芳基卤化物来合成 5-
HMF 的芳基酯。在这里,我们研究了聚
苯乙烯载体的重要作用,以避免众所周知的 5-
HMF 脱羰。该反应具有广泛的底物范围,具有相当好的收率和催化剂的可回收性。
