    The invention provides novel processes for the preparation of fluorinated acyl fluorides and fluorinated vinyl ethers, i.e., a process for the preparation of fluorinated acyl fluorides (3) which comprises reacting a compound (1) having a fluorine content of 30 % by mass or above with fluorine in a liquid phase to thereby obtain a compound (2) and subjecting the compound (2) to ester linkage cleavage, and a process for the preparation of fluorinated vinyl ethers (10) which comprises subjecting a fluorinated acyl fluoride (3) to pyrolysis. In the formulae, R<A> and R<B> are each alkyl or the like, or alternatively R<A> and R<B> may be united to form alkylene containing one or more etheric oxygen atoms, or the like; R<C> and R<D> are each perfluoroalkyl containing one or more etheric oxygen atoms, or the like, or alternatively R<C> and R<D> may be united to form perfluoroalkylene containing one or more etheric oxygen atoms, or the like; X<1> to X<6> are each hydrogen, fluoro, or the like; and R<AF>, R<BF>, R<CF> and R<DF> are groups derived respectively from R<A>, R<B>, R<C> and R<D> by replacing substantially all of the hydrogen atoms by fluorine atoms, or the like.
