PROCESS FOR THE PREPARATION OF BENZOIC ACID DERIVATIVES VIA A NEW INTERMEDIATE OF SYNTHESIS

摘要

The object of the invention is the preparation of 2-chloro-4-fluoro-5-nitrobenzoic acid and derivatives thereof, by nitration of 2-chloro-4-fuorobenzotrichloride and the conversion of the novel synthetic intermediate thus obtained into its acid form or derivatives thereof; a further object of the invention is the conversion of benzotrichloride synthetic intermediates into the corresponding benzotrifluoride derivatives.
