Disclosed is a method for preparing a 2,5-disubstituted furan compound. The 2,5-disubstituted furan compound is prepared in a simple, convenient and highly efficient way by reacting 2,3-dicarboxylic anhydride-7-oxabicyclo[2.2.1]hept-5-ene and/or furan with an acylating reagent and/or an alkylating reagent. The preparation method is simple and efficient, has a short process and less by-products, and the 2,5-disubstituted furan compound prepared by using the method has a high purity, and can satisfy the requirements for being used as a raw material for engineering plastics, such as high-performance polyesters, epoxy resins, polyamides, polyurethanes and the like, and as a chemical raw material and a pharmaceutical intermediate raw material.
揭示了一种制备2,5-二取代呋喃化合物的方法。通过将2,3-二羧酸酐-7-氧杂双环[2.2.1]庚-5-烯和/或呋喃与酰化试剂和/或烷基化试剂反应,以简单、方便和高效的方式制备2,5-二取代呋喃化合物。该制备方法简单高效,过程短,副产物少,采用该方法制备的2,5-二取代呋喃化合物纯度高,可满足作为工程塑料原料(如高性能聚酯、环氧树脂、聚酰胺、聚氨酯等)和化工原料、药物中间体原料的要求。
