    • Inorganic and organic compounds containing fluorine can be produced, for example, from corresponding chlorine-containing compounds by chlorine/fluorine exchange using fluorinating agents. Monocyclic or bicyclic compounds containing at least two nitrogen atoms, at least one of which is incorporated into the ring system, can be used as catalysts or fluorinating agents for chlorine/fluorine exchange reactions to produce sulfurylchlorofluoride, sulfurylfluoride or a carboxylic acid fluoride. It is likewise possible to carry out HF addition to unsaturated carbon-carbon bonds or chlorine/fluorine exchange at carbon atoms. For example, monochloro or dichloro malonic acid esters can be converted to difluoro malonic acid esters. Work-up of the reaction mixture can be simplified by using suitable solvents which force the reaction mixture to exist in two phases.
    • 含氟的无机和有机化合物可以例如通过使用氟化剂的氯/氟交换从相应的含氯化合物制备。 含有至少两个氮原子(其中至少一个被引入环系中)的单环或双环化合物可以用作氯/氟交换反应的催化剂或氟化剂,以产生磺酰氯,磺酰氟或羧酸氟化物。 同样可以在碳原子处进行HF添加到不饱和碳 - 碳键或氯/氟交换。 例如,一氯或二氯丙二酸酯可以转化为二氟丙二酸酯。 反应混合物的后处理可以通过使用强制反应混合物在两相中存在的合适的溶剂来简化。
