A process for preparing fluorine-containing compounds fluorine-halogen exchange using special catalysts Polyaminophosphazen

A process for producing fluorine-containing compounds by reaction of a compound containing replaced by fluorine halogen with a fluoride or a mixture of fluorides of the general formula I MeF A DOLLAR DOLLAR A wherein Me is an alkaline earth metal, NH¶4¶ · + · ion or alkali metal ion, in the presence or absence of a solvent at a temperature of 60 to 260 ° C, characterized in that DOLLAR F1 that the reaction in the presence of a compound or mixture of compounds of general formula (IIa) and / or ( IIb) is carried out, DOLLAR a wherein a · 1 · to a · 24 · are independently, the same or different and represent 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 standing to 12 carbon atoms, an aralkyl having 7 to 12 carbon atoms, or a · 1 · -A · 2 · a · 3 · -A x 4 x, a x 5 x -A · 6 · etc. to a · 23 · -A · 2 are 4 x are independently, the same or different and are directly or via O or NA x 25 x connected to each other to form a ring having 3 to 7 ring members, A · 25 · is an alkyl having 1 to 4 carbon atoms, wherein X · 1 · and / or X * 2 * and / or X · having 3 · independently radicals of the formula (IIc), or the radicals X X 1 X and / or X * 2 * and / or X * 3 * also branched for a straight-chain or alkyl or alkenyl having 1 to 12 carbon atoms, cycloalkyl having 4 to 8 carbon atoms, an aryl having 6 to 12 carbon atoms, a ...
