Herein, a robust catalytic system was developed for the green synthesis of 5-methylfurfural (5-MF) by iodide-mediated transfer hydrogenation. Around 50 % of 5-MF was yielded from d-fructose within 7.5 min using NaI as the catalyst and formic acid as both the hydrogen source and co-catalyst. The catalytic system was used for six consecutive cycles without any decrease in the yield. Various starch and raw biomass could be used as promising starting materials for 5-MF synthesis with moderate yields, and the productivity of 5-MF from corn starch reached 103 mmol g h , which is comparable with the best result from l-rhamnose. Moreover, the co-production of 5-MF and furfural from raw biomass makes this methodology more competitive than other routes.
本文开发了一种通过碘介导转移氢化反应绿色合成 5-甲基糠醛（5-MF）的稳健催化体系。使用碘化钠作为催化剂，甲酸作为氢源和共催化剂，在 7.5 分钟内可以从 d-果糖中得到约 50%的 5-MF。该催化体系在六个连续循环中没有任何产率下降。各种淀粉和原料生物质可以作为 5-MF 合成的有前途的起始原料，具有中等产率，玉米淀粉的 5-MF 生产力达到 103mmol·g-1·h-1，与 l-鼠李糖的最佳结果相当。此外，从原料生物质中同时生产 5-MF 和糠醛使得这种方法比其他路线更具竞争力。
