An iron-catalyzed efficient valorization of biomass-derived furfural (FUR) in aliphatic alcohols is developed in which product selectivity can be simply regulated by varying the gas atmosphere. In the presence of molecular oxygen, there is oxidative condensation of FUR with ethanol, and the obtained product is furan-2-acrolein in a “FUR-ethanol-O₂” system. Under suitable conditions, the conversion of FUR and selectivity of furan-2-acrolein are 84.2% and 82.7%, respectively. In the presence of H₂, the selective hydrogenation of FUR is achieved, and the main product is furfuryl alcohol in a “FUR-ethanol-H₂” system. Under optimal conditions, a 99.9% conversion of FUR and 93.6% selectivity of furfuryl alcohol are attained. This provides an economic, green and sustainable method for the utilization of biomass-based platform compounds in the chemical industry.

铁的多功能催化：脂肪醇中生物质衍生糠醛的可调和选择性转化

在脂肪醇中开发了铁催化的生物质衍生糠醛（FUR）的有效增值，通过改变气体气氛可以简单地调节产物的选择性。在分子氧的存在下，FUR与乙醇发生氧化缩合，所得产物为“ FUR-乙醇-O ₂ ”系统中的呋喃-2-丙烯醛。在合适的条件下，FUR的转化率和呋喃-2-丙烯醛的选择性分别为84.2％和82.7％。在H ₂的存在下，实现了FUR的选择性加氢，主要产物是糠醇，在“ FUR-乙醇-H ₂“ 系统。在最佳条件下，可获得99.9％的FUR转化率和93.6％的糠醇选择性。这为化学工业中基于生物质的平台化合物的利用提供了一种经济，绿色和可持续的方法。
