4-Fluorosalicylic acid derivatives represented by general formula (1) and a process for producing the same, wherein X1, X2, and X3 each independently represents hydrogen or halogeno, exclusive of the case where all of X1, X2, and X3 are hydrogen or fluorine at the same time. The 4-fluorosalicylic acid derivatives are novel compounds not found in the literature. They can be easily converted to 3-fluorophenol derivatives extremely useful as liquid crystals, recording materials, and intermediates for drugs and agricultural chemicals. They are highly suitable for use as intermediates for the 3-fluorophenol derivatives.
由通式(1)表示的4-氟水杨酸衍生物及其生产工艺,其中X1、X2和X3各自独立地代表氢或卤素,不包括所有X1、X2和X3同时为氢或氟的情况。4-氟水杨酸衍生物是文献中未发现的新型化合物。它们可以很容易地转化为 3-氟苯酚衍生物,作为液晶、记录材料以及药物和农药的中间体非常有用。它们非常适合用作 3-氟苯酚衍生物的中间体。
