In the present work, an alternative system of 5-hydroxymethylfurfural (HMF) oxidation was studied, in an attempt to avoid the use of expensive metal catalysts, polluting systems and high pressures. In this context, the partial oxidation of the hydroxyl group on the HMF molecule leads to the formation of the corresponding aldehyde, 2,5-diformylfuran (DFF). This reaction was catalyzed by 2-iodobenzenesulfonic acid in the presence of oxone. Under optimized experimental conditions, the HMF conversion was found to be 100%, while the DFF yield and selectivity were almost 90%.

在内酯存在下并由2-碘代苯磺酸催化的克规模的5-羟甲基糠醛选择性氧化为二甲酰基呋喃

在当前的工作中，研究了5-羟甲基糠醛（HMF）氧化的替代系统，试图避免使用昂贵的金属催化剂，污染系统和高压。在这种情况下，HMF分子上的羟基的部分氧化导致形成相应的醛2，5-二甲酰呋喃（DFF）。该反应由2-碘苯磺酸在氧杂酮存在下催化。在优化的实验条件下，发现HMF的转化率为100％，而DFF的收率和选择性几乎为90％。
