A method for producing a fluoromethyl derivative represented by formula (1), the method including step A of reacting an alkene compound represented by formula (2) with a fluorine source represented by formula MF
n
, 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.
An object of the present invention is to provide a method for producing a fluorinated organic compound, whereby an iodosylbenzene derivative can be easily separated and recovered. The above object can be achieved by a method for producing a fluorinated organic compound, comprising step A of fluorinating an organic compound (1) by reaction with a fluorine source (3) in the presence of a hypervalent iodine aromatic ring compound (2a), or in the presence of an iodine aromatic ring compound (2b) and an oxidant (2bo); wherein the fluorine source (3) is a fluorine source (3a) represented by formula: MF
n
, wherein M is 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; and step B of separating the iodine aromatic ring compound from a reaction liquid after step A is started.
