A process for the preparation of substantially fluorinated alkyl bromides from the corresponding iodides is described. At least one anhydrous metal bromide, which can contain certain metals as the cation, is reacted at 80 DEG to 450 DEG C. under atmospheric pressure or the autogenous pressure of the reaction mixture and with good mixing, with the substantially fluorinated alkyl iodide, without the addition of other substances. The new process achieves good yields of substantially fluorinated alkyl bromides and requires no special safety precautions.
