Nuclear fluorinated phthaloyl and terephthaloyl fluorides, especially tetrafluoroterephthaloyl fluoride, are obtained by reacting a corresponding nuclear chlorinated acid halide with potassium fluoride in a polar aprotic solvent, preferably sulpholane, at a temperature of from 100 to 200°C, preferably 120 to 150°C.
The products are useful chemical intermediates for the synthesis of pesticides.
核氟化邻苯二甲酰基和对苯二甲酰基氟化物,特别是四氟对苯二甲酰基氟化物,是通过在极性非丙烷溶剂(最好是磺烷)中,在 100 至 200℃,最好是 120 至 150℃的温度下,使相应的核氯化酸卤化物与氟化钾反应而得到的。
这些产品是合成杀虫剂的有用化学中间体。
