A halogenating agent is added to a mixture including a base, a fluoroalkylcarboxylic acid derivative and an acrylate derivative to produce a fluoroaclyacetic acid derivative represented by the following Formula (3):
wherein Rf represents a fluorine containing alkyl group, R1 and R2 represent a hydrogen atom, an alkyl group, a cycloalkyl group, an aryl group, an arylalkyl grou p or an acyl group, or together represent an atomic group that forms a 5- or 6-memb ered ring containing a nitrogen atom to which R1 and R2 are bonded; R3 represents a hydrogen atom, an alkyl group, a cycloalkyl group, an aryl group, or an arylalkyl g roup; and R4 represents an alkyl group, a cycloalkyl group, an aryl group, or an aryl alkyl group.
在包括碱、氟烷基羧酸衍生物和丙烯酸酯衍生物的混合物中加入卤化剂,生成由下式(3)表示的氟乙酸衍生物:
其中 Rf 代表含氟烷基,R1 和 R2 代表氢原子、烷基、环烷基、芳基、芳烷基或酰基,或共同 代表一个原子团,该原子团形成一个含有氮原子的 5 或 6 嵌合环,R1 和 R2 与该环键合;R3 代表氢原子、烷基、环烷基、芳基或芳基烷基团;以及 R4 代表烷基、环烷基、芳基或芳基烷基团。
