Perfluoroalkyl aromatic compounds are prepared by reacting an aromatic bromide or iodide with at least about one equivalent of an organic acid salt corresponding to the formula set forth below in the presence of cuprous iodide and a diploar aprotic solvent:
in which M is potassium or -NR¹R²R³R⁴; R¹, R², R³ and R⁴ are the same or different alkyl groups containing from 1 to 20 carbon atoms, and n is 0 when M is -NR¹R²R³R⁴ and 0 or an interger of at least 1 when M is potassium.
全氟烷基芳香族化合物的制备方法是,在碘化亚铜和二元烷基非沸腾溶剂存在下,将芳香族溴化物或碘化物与至少约一个当量的符合下式的有机酸盐反应:
其中 M 为钾或-NR¹R²R³R⁴;R¹、R²、R³ 和 R⁴ 为相同或不同的含 1 至 20 个碳原子的烷基,当 M 为-NR¹R²R³R⁴时,n 为 0;当 M 为钾时,n 为 0 或至少为 1 的中间值。
