    wherein two R1 are the same and each is a fluorine atom or a fluoroalkyl group,
    the method comprising step A of reacting a compound represented by formula (2):

    wherein R1 is as defined above, with a compound (3) represented by formula (3-1) or the like:

    wherein R31, R32, and R33 are the same or different and each is a hydrogen atom or a C1-10 alkyl group, or two of them are optionally linked to each other to form a ring optionally having one or more substituents,
    in the presence of a fluorine compound (4) represented by formula (4-1) or the like:

             MHnFm     (4-1)

    wherein M is a metal atom, n is 0 or 1, and the sum of the valence number of M and n is m, and

    摘要： The invention provides a method for easily and simply producing a cyclic carbonate containing an unsaturated group. The method is a method for producing a cyclic carbonate represented by the following formula (1):

    wherein X 1 and X 2 are the same as or different from each other, and are each a hydrogen atom, a fluorine atom, or a monovalent organic group; and R is an organic group containing one or more carbon-carbon unsaturated bonds. The method includes reacting an unsaturated cyclic carbonate represented by the following formula (A):

    wherein X 1 and X 2 are defined as described above, and an alcohol represented by the formula (B): R-OH, wherein R is defined as described above, or an alkoxide thereof in the presence of a base, or reacting the unsaturated cyclic carbonate and the alkoxide.

    摘要： This invention provides a composition that contains PFOB with a PFOA content lower than that of known PFOB, and that is less likely to have an adverse effect on the environment; and provides a method for producing PFOB. The composition contains C 8 F 17 Brand further contains C 7 F 15 COOH, wherein C 7 F 15 COOH is present in a concentration of 25 ppb or less based on the total weight of C 8 F 17 Br. The method for producing C 8 F 17 Br comprises reacting C 8 F 17 I and a brominating agent to obtain C 8 F 17 Br, and alkali-washing the obtained C 8 F 17 Br to reduce the C 7 F 15 COOH content to 25 ppb or less based on the total weight of C 8 F 17 Br.
