A process for the preparation of an ester, especially fluorinated esters R.sub.1 O.OC--CHR.sub.2 --CO.OR.sub.3, R.sub.1 and R.sub.3 are each independently selected from alkyl, cycloalkyl and aryl. R.sub.2 is selected from hydrogen, alkyl, cycloalkyl. The method includes the steps of covering a corresponding compound of formula 2: R.sub.1 O.OC--CHR.sub.2 --CO.OR.sub.3 in the presence of a base, of salt of a compound of formula 2, into corresponding compound of formula 1 by the reaction of elemental fluorine.
一种制备酯的方法,特别是氟化酯R.sub.1 O.OC-CHR.sub.2-CO.OR.sub.3,其中R.sub.1和R.sub.3各自独立选择自烷基,环烷基和芳基。R.sub.2选择自氢,烷基,环烷基。该方法包括以下步骤:在碱存在下,将式2的相应化合物R.sub.1 O.OC-CHR.sub.2-CO.OR.sub.3与化合物的盐覆盖,通过元素氟反应将其转化为式1的相应化合物。
