The present invention provides a process for producing a linear perfluoroalkanone or a perfluorocycloalkanone, which comprises using as a starting material a combination of the same or different kinds of compounds that are selected from perfluoroalkanoyl halides represented by the formula: F(CF
2
)
n
COX wherein X is F, Cl, Br or I and n is an integer of 1 to 8, or a perfluoroalkanedioyl dihalide represented by the formula: XOC(CF
2
)
n
COX wherein X is F, Cl, Br or I and n is an integer of 3 to 8, and reacting the starting material with a metal carbonate or metal carbonates. According to the present invention, perfluoroalkanones can be produced with a good yield from relatively easily available starting materials by a simple synthesis method.
