Abstract
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 R—COOCF—Rand R—CHOH are subjected to a transesterification reaction to obtain R—COOCH—R, and a fluorination step in which the obtained compound is fluorinated to obtain a reaction product containing R—COOCF—R. Here, in the formulae, Ris a monovalent organic group, and Ris the same group as Ror a monovalent organic group obtained by fluorination of R.
