本网讯 近日，石化新材料与资源精细利用国家地方联合工程实验室肖毅博士研究组最新成果在Molecular Catalysis发表。论文题目为“Ionic liquid-assisted catalytic oxidation of anethole by copper- and iron-based metal-organic frameworks”，全文摘要如下：A synergistic strategy involving ionic liquid (IL) and Cu- or Fe-based metal-organic frameworks (MOFs) has been developed for the selective oxidation of anethole with H₂O₂andtert-butyl hydroperoxide (TBHP). Under the optimum conditions, 74.8%–91.5% conversion of substrate and 92.1%–94.6% selectivity for anisaldehyde were obtained overCu-BTC-1(BTC: benzene-1,3,5-tricarboxylate) with the aid of 5.0 mol% [C₁₂mim]Cl using aqueous H₂O₂as the oxygen source. In contrast,Fe(PMA)(PMA: pyromellitate) nanorods provided up to 84.0% yield of 4-methoxyphenylacetone in the presence of 5.0 mol% [C₄mim][Cys] by using TBHP oxidant. Notably, amphiphilic [C₁₂mim]Cl and multifunctional [C₄mim][Cys] are favorable for the improved reactivity and good reusability ofCu-BTC-1orFe(PMA)owing to the synergistic effects ofCu-BTC-1/[C₁₂mim]Cl orFe(PMA)/[C₄mim][Cys] nano/submicro-structures fabricatedin-situ. In particular, nanoscale stacking of [C₄mim][Cys] onFe(PMA)can be directly demonstrated by TEM. In-depth understanding of the reaction mechanism can be achieved using XRD, FT-IR, DRUV-vis and UV–vis techniques。
