A process is disclosed for preparing fluorine-containing compounds by reacting a compound which contains a halogen that can be replaced by fluorine with a fluoride or a mixture of fluorides of general formula (I) MeF, in the presence of a compound or of a mixture of compounds of general formula (II), and in the presence or absence of a solvent, at a temperature from 40 to 260 ~C. In the formula (I), Me stands for an alkaline earth metal ion, an NH4+ ion or an alkali metal ion. In the formula (II), A1, A2, A3, A4, A5, A6, A7, A8 are the same or different and independently represent a straight or branched-chain alkyl or alkenyl with 1 to 12 carbon atoms, cycloalkyl with 4 to 8 carbon atoms, aryl with 6 to 12 carbon atoms, aralkyl with 7 to 12 carbon atoms, or A1A2, A3A4, A5A6, A7A8 are the same or different and are directly joined by O or N-A9 into a ring with 3 to 7 members; A9 stands for an alkyl with 1 to 4 carbon atoms and B- stands for a monovalent acid radical or for the equivalent of a polyvalent acid radical.
