Abstract
The present invention provides a method for producing a fluorine-containing halide, comprising reacting a fluorine-containing sulfonyl halide or fluorine-containing disulfonyl chloride with a metal halide or metal component in the present or absence of a solvent. In accordance with the present invention, a fluorine-containing bromide, fluorine-containing iodide or fluorine-containing chloride can be readily produced in high yield at low cost, using an industrially advantageous process.
