Process for preparing compounds containing fluorine The present invention relates to 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 I MeF (I), in which Me is an alkaline earth metal ion, NH4+-ion or alkali metal ion, in the presence of a compound or a mixture of compounds of the formula (II) Image in which A1, A2, A3, A4, A5, A6, A7, A8 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 A1 A2, A3A4, A5A6, and A7A8 independently of one another are identical or different and are connected to one another directly or by way of O or N-A9 to form a ring having 3 to 7 ring members, A9 is an alkyl having 1 to 4 carbon atoms and B- is a monovalent acid radical or the equivalent of a polyvalent acid radical, in the presence or absence of a solvent at a temperature from 40 to 260°C.

L'invention concerne un procédé de préparation de composés fluorés, selon lequel on fait réagir un composé qui contient un halogène remplaçable par du fluor avec un fluorure ou un mélange de fluorures de formule générale (I): MeF, en présence d'un composé ou d'un mélange de composés de formule générale (II) et en présence ou en l'absence d'un solvant, à une température de 40 à 260 DEG C. Dans la formule (I), Me désigne un ion d'un métal alcalino-terreux, de NH4<+> ou d'un métal alcalin. Dans la formule (II), A<1>, A<2>, A<3>, A<4>, A<5>, A<6>, A<7>, A<8> sont identiques ou différents et représentent, indépendamment les uns des autres, un alkyle ou un alcényle à chaîne droite ou ramifiée possédant 1 à 12 atomes de carbone, un cycloalkyle de 4 à 8 atomes de carbone, un aryle de 6 à 12 atomes de carbone, un aralkyle de 7 à 12 atomes de carbone, ou bien A<1>A<2>, A<3>A<4>, A<5>A<6>, A<7>A<8> sont identiques ou différents et sont directement reliés par O ou N-A<9> de façon à former un cycle de 3 à 7 chaînons; A<9> désigne un alkyle de 1 à 4 atomes de carbone et B<-> désigne un radical acide monovalent ou l'équivalent d'un radical acide polyvalent.
