Abstract:
A process for preparing fluorine-containing compounds by reacting a compound which contains fluorine-exchangeable halogen with a fluoride or a mixture of fluorides with the formula IMeF (I),in which Me is an alkaline earth metal ion, NH.sub.4.sup.+ -ion or alkali metal ion, in the presence or absence of a solvent at a temperature from 40 to 260.degree. C., which comprises carrying out the reaction in the presence of a compound or a mixture of compounds of the formula (II) ##STR9##in which A.sup.1, A.sup.2, A.sup.3, A.sup.4, A.sup.5, A.sup.6, A.sup.7, A.sup.8 independently of one another are identical or different and are a straight-chain or branched alkyl or alkenyl having 1 to 12 carbon atoms, cycloalkyl having 4 to 8 carbon atoms, an aryl having 6 to 12 carbon atoms, or an aralkyl having 7 to 12 carbon atoms, or A.sup.1 A.sup.2, A.sup.3 A.sup.4, A.sup.5 A.sup.6, and A.sup.7 A.sup.8 independently of one another are identical or different and are connected to one another directly or by way of O or N--A.sup.9 to form a ring having 3 to 7 ring members, A.sup.9 is an alkyl having 1 to 4 carbon atoms and B.sup.- is a monovalent acid radical or the equivalent of a polyvalent acid radical.
