A process for production of 2-fluor ocyclopropane-1-carboxylic esters, characterized by reacting a compound represented by the general formula (1) with a reducing agent in the presence of a phase transfer catalyst: (1) wherein X is chloro, bromo, or iodo; and R<1> is alkyl having 1 to 8 carbon atoms, aryl having 6 to 12 carbon atoms, alkenyl having 2 to 8 carbon atoms, or aralkyl composed of aryl having 6 to 12 carbon atoms and alkylene having 1 to 6 carbon atoms. According to the process, the reaction time of dehalogenation can be remarkably shortened.
(ZH) 2-氟环丙烷-1-羧酸酯的制备方法,该方法的特征在于,在相间转移催化剂的存在下,使下式(1):表示的化合物与还原剂反应,式中,X表示氯原子、溴原子或碘原子;R1表示碳原子数1~8的烷基、碳原子数6~12的芳基、碳原子数2~8的链烯基或由碳原子数6~12的芳基和碳原子数1~6的亚烷基构成的芳烷基。采用本发明的制备方法能够大幅度缩短脱卤反应的反应时间。
