Abstract

Iodoxybenzoic acid (IBX) supported multi walled carbon nanotube (MWCNT) derivatives have been prepared as easily recyclable solid reagents. These compounds have been shown to be able to mimic the alcohol dehydrogenases and monooxygenases promoted oxidation of aromatic alcohols to corresponding aldehydes. Their reactivity was found to be dependent on the degree of functionalization of MWCNTs as well as from the chemical properties of the spacers used to bind IBX on the surface of the support. Au-decorated MWCNTs and the presence of longer spacers resulted in the optimal experimental conditions. A high conversion of the substrates and yield of desired products were obtained.

摘要

碘代苯甲酸（IBX）负载的多壁碳纳米管（MWCNT）衍生物已被制备为易于回收的固体试剂。这些化合物已被证明能够模拟醇脱氢酶和单加氧酶促进的芳香醇氧化为相应醛的反应。发现它们的反应活性取决于多壁碳纳米管的功能化程度以及用于将IBX连接到载体表面的间隔基的化学性质。金修饰的多壁碳纳米管和较长间隔基的存在导致了最佳实验条件。获得了底物的高转化率和所需产物的高收率。
