An azobenzene derivative, 6,6'-difluoro-2,2'- dinitroazobenzene, is obtained in high yield (almost double) compared to other halogenated derivatives (2). Also, the fluorines on 6,6'-difluoro-2,2'- dinitroazobenzene can be easily displaced, thus allowing nucleophilic displacement to produce other derivatives. Optimizing the synthesis of 6,6'- difluoro-2,2'-dinitroazobenzene from 2-fluoro-6-nitroaniline by studying the effects of several reaction conditions, including heat, solvent, and concentration of oxidizing agent, will eventually and potentially lead to a route that produces the highest yield.
