Abstract
An object of the present invention is to provide a method for producing a fluorinated organic compound with a high yield without using carbon tetrachloride in view of the fact that the production of a fluorinated organic compound with a sufficient yield was impossible for a hitherto-known method that uses a fluorinating agent that contains IF-pyridine-HF alone. Another object of the present invention is to provide a fluorinating reagent that is capable of achieving this object. The present invention provides a composition comprising (1) IFand (2) an aprotic solvent (with the proviso that carbon tetrachloride is excluded), wherein the aprotic solvent is contained in an amount within a range of 50 mass ppm to 20 mass %.
