摘要： A process for producing a fluorinated ester through a small number of steps, is presented. The process for producing a fluorinated ester, comprises a transesterification step in which RAF—COOCF2—RAF and RA—CH2OH are subjected to a transesterification reaction to obtain RAF—COOCH2—RA, and a fluorination step in which the obtained compound is fluorinated to obtain a reaction product containing RAF—COOCF2—RAF. Here, in the formulae, RA is a monovalent organic group, and RAF is the same group as RA or a monovalent organic group obtained by fluorination of RA.
