The present invention provides a process whereby fluorinated ketones of various structures can be produced by short process steps and which is useful as an industrial production process. Namely, it is a process for producing a fluorinated ketone of the following formula (5), which comprises reacting a compound of the following formula (3) having a fluorine content of at least 30 mass%, with fluorine in a liquid phase to obtain a compound of the following formula (4), and then, subjecting the ester linkage of the compound of the formula (4) to a dissociation reaction: R<C>COOCHR<A>R<B> R<CF>COOCFR<AF>R<BF> R<AF>R<BF>C=O wherein each of R<A> and R<AF> are each a monovalent organic group such as an alkyl group, or R<A> and R<B> may be bonded to each other to form a bivalent organic group such as an alkylene group, R<AF> and R<BF> are a monovalent organic group such as a perfluoroalkyl group formed by fluorination of R<A> and R<B>, or they are bonded to each other to form a bivalent organic group such as a perfluoroalkylene group, and R<C> and R<CF> are each a monovalent organic group such as a perfluoroalkyl group which may contain an etheric oxygen atom. |
