Demonstrated herein is the highly efficient synthetic protocol for the conversion of mucic acid into adipic acid through the oxorhenium‐complex‐catalyzed deoxydehydration (DODH) reaction and subsequent Pt/C‐catalyzed transfer hydrogenation. Quantitative yields (99 %) were achieved for the conversion of mucic acid into muconic acid and adipic acid either in separate sequences or in a one‐step process.
用可再生的生物基原料生产散装化学品和燃料对于人类社会的可持续发展具有重要意义。己二酸是生物资源中需求最旺盛的直接化学药品之一,主要用于尼龙6,6聚酰胺的大批量生产。迫切需要开发可持续和环境友好的方法,以从可再生原料生产己二酸。但是,目前没有合适的生物己二酸合成工艺。本文展示了一种高效的合成方案,可通过氧化or络合物催化的脱氧脱水(DODH)反应以及随后的Pt / C催化的转移氢化将黏性酸转化为己二酸。
