    摘要: An object of the present disclosure is to provide a novel method for producing a fluoromethyl derivative. The object is achieved by a method for producing a fluorinated organic compound represented by formula (1):

    wherein
    R 1 represents an organic group,
    R 2 represents hydrogen, halogen, or an organic group,
    R 3 represents hydrogen, halogen, or an organic group,
    L represents a single bond, alkanediyl, -CO-, -CONR-, -NRCO-, -O-CO-, or -CO-O- wherein R independently represents, in each occurrence, hydrogen or an organic group,
    R 4 represents hydrogen, halogen, hydroxyl, or an organic group,
    R 3 and R 4 may be linked to each other, and
    R X represents hydrogen or fluoro,
    provided that when R 4 represents hydrogen, L represents -CO-, -CONR-, -NRCO-, -O-CO-, or -CO-O-,
    the method including step A of reacting an alkene compound represented by formula (2):
    wherein the steric configuration of a single bond indicated by a wavy line with respect to a double bond to which the single bond is connected is in E configuration or Z configuration, or a mixture of E configuration and Z configuration in any ratio, and other alphabetical symbols are as defined above,
    with a fluorine source that is a fluorine source (3a) represented by formula MF n wherein M represents H, a metal of Group 1 of the periodic table, or a metal of Group 2 of the periodic table; and n is 1 or 2
    in the presence of a hypervalent-iodine aromatic compound (1a), or
    in the presence of an aromatic iodine compound (1b) and an oxidant (A) to fluorinate the alkene compound.

    摘要: The invention provides a novel method for producing a fluorinated organic compound. The method for producing a fluorinated organic compound comprises reacting a compound represented by formula (1):

    (wherein R 1 and R 2 are each independently a hydrogen atom, a halogen atom, or an organic group, or R 1 and R 2 optionally form a ring together with the two adjacent carbon atoms; n is 1 or 2;
    and wherein two R 1 s are optionally the same or different, two R 2 s are optionally the same or different, or two R 1 s or two R 2 s optionally form a ring together with their adjacent carbon atom), with (A) at least one fluorine source selected from the group consisting of hydrogen fluoride, hydrogen fluoride salts, and fluoride salts, and (B) a halogen source other than fluorine represented by the formula: R 3 (OX) m (wherein R 3 is a hydrogen atom, a cation, or an organic group, X is a halogen atom other than a fluorine atom, and m is an integer corresponding to the valence of R 3 ), to add fluorine and a halogen other than fluorine to the double bond or triple bond.
