The conversion of biomass to a high value-added product 1, 4-butanediol (BDO) and its derivatives is of great economic significance. In this work, furancarboxylic acid (FCA) was adopted as the raw material to prepare BDO. The one-pot synthesis of 1, 4-butanediol diacetate (BDA) has been successfully prepared from FCA with metal triflates and Pd/C catalysts. The effect of reaction conditions was investigated and the reaction routes was systematically studied by ¹H-NMR and GC. The tandem catalytic process from FCA to BDA mainly underwent three stages. Firstly, FCA was hydrogenated to tetrahydrofurfuric acid (THFCA) by Pd/C. Afterwards, THFCA was decarbonylated to form oxonium ions with metal triflates. Then the oxonium ions was rapidly hydrogenated to form tetrahydrofuran (THF) by Pd/C. Ultimately, THF was ring-opening esterified to BDA by metal triflates. This novel synthesis method of BDO from FCA provides a promising protocol for broadening the application of common biomass substrates.

将生物质转化为高附加值产品1、4-丁二醇（BDO）及其衍生物具有重要的经济意义。在这项工作中，呋喃羧酸（FCA）被用作制备BDO的原料。1，FCA与三氟甲磺酸金属盐和Pd / C催化剂已成功制备出一锅法合成1,4-丁二醇二乙酸酯（BDA）。反应条件的影响进行了研究，并将反应路线进行了系统研究由¹1 H-NMR和GC。从FCA到BDA的串联催化过程主要经历了三个阶段。首先，通过Pd / C将FCA氢化为四氢糠酸（THFCA）。之后，THFCA与金属三氟甲磺酸酯脱羰形成氧鎓离子。然后，通过Pd / C将氧鎓离子快速氢化以形成四氢呋喃（THF）。最终，THF被金属三氟甲磺酸酯开环酯化为BDA。从FCA合成BDO的这种新颖方法为扩大常见生物质底物的应用提供了有希望的协议。
