    摘要： The purpose of the present invention is to obtain a fluorine-containing compound which is easily stabilized without irradiation of ultraviolet light, by efficiently converting a C—I bond in an iodine-containing compound having a group represented by —CFRf—I (wherein Rf is a fluorine atom or a perfluoroalkyl group) to a C—H bond. A method for producing a fluorine-containing compound having an iodine atom content reduced than the following iodine-containing compound, which comprises subjecting an iodine-containing compound having a group represented by —CFRf—I (wherein Rf is a fluorine atom or a perfluoroalkyl group) to deiodinating treatment in the presence of an organic peroxide and a hydrogen-containing compound having a group represented by —CHR1—CHR2—CHR3— (wherein R1, R2 and R3 are each independently a hydrogen atom or an alkyl group).
