Abstract
A process for producing aromatic compounds comprises the step of carrying out a reaction between an aromatic carboxylic acid and a polyfluorobenzonitrile, thus forming an aromatic nitrile and a polyfluorobenzene. This process can produce the aromatic compounds with few problems with respect to worker safety and at a low cost when compared with conventional processes, and can convert the starting materials for the reaction into useful substances with ease and little waste and in a high yield.
