α-Monofluoroalkanoic acids are important intermediates in the synthesis of biologically active fluorine compounds. General methods of preparation have been examined, based on the three following reagents: (a) hydrogen fluoride + N-bromoacetamide; (b) diethyl monofluoromalonate; and (c) perchloryl fluoride. The first of these is the recommended procedure for simple unsubstituted α-fluoro acids; however, the
α-单氟链烷酸是合成生物活性氟化合物的重要中间体。已根据以下三种试剂检查了一般制备方法: (a) 氟化氢 + N-溴乙酰胺;(b) 单氟丙二酸二乙酯;(c) 全氯酰氟。其中第一个是简单的未取代 α-氟酸的推荐程序;然而,氟丙二酸路线不太活跃,因此是那些含有不稳定官能团的 α-氟代酸的首选方法。
