PROCESSES FOR PRODUCING FLUORINATED ESTER, FLUORINATED ACYL FLUORIDE, AND FLUORINATED VINYL ETHER

Document Type and Number:

WIPO Patent Application WO/2002/055471

Kind Code:

A1

Abstract:

A process for producing a fluorinated ester through a small number of steps. The process is characterized by comprising: a transesterification step in which R?AF¿-COOCF¿2?-R?AF¿ and R?A¿-CH¿2?OH are subjected to transesterification to thereby obtain R?AF¿-COOCH¿2?-R?A¿; and a fluorination step in which the compound obtained is fluorinated in a liquid phase to obtain a reaction product containing R?AF¿-COOCF¿2?-R?AF¿. In the formulae, R?A¿ is a monovalent organic group and R?AF¿ is the same group as R?A¿ or is a monovalent organic group obtained through fluorination of R?A¿.
