A process for the preparation of a compound of Formula A:
wherein
X¹ and X²are independently selected from H or any substituent which does not interfere with the electrochemical reductive fluorination; and
Z¹ and Z²are each independently selected from H or an electron donating group;
which comprises electrochemical reductive fluorination of a compound of Formula B:
wherein X¹, X², Z¹ and Z² are as defined above in a mixture of anhydrous hydrogen fluoride and an alkali metal fluoride.
The 4-fluoroanilines find use as intermediates in the manufacture of a wide range of agrochemicals, dyestuffs and pharmaceuticals.
一种制备式 A 化合物的工艺:
其中
X¹ 和 X² 分别独立地选自 H 或任何不干扰电化学还原氟化反应的取代基;以及
Z¹ 和 Z² 各自独立地选自 H 或电子捐赠基团;
其中包括式 B 化合物的电化学还原氟化反应:
其中X¹、X²、Z¹和Z²如上定义,在无水氟化氢和碱金属氟化物的混合物中。
4-氟苯胺可用作生产多种农用化学品、染料和药品的中间体。
