Electrophilic substitution in 2- and 4-(trifluoromethyl)imidazoles provides derivatives containing one or two nitro, chloro, bromo, or iodo groups. Fluoro and chloro derivatives were also prepared by photochemical trifluoromethylation of the respective haloimidazole. The results demonstrate that (trifluoromethyl)imidazoles behave fairly typically under the conditions of electrophilic nitration and halogenation. Of the alternative routes to the desired bifunctional and trifunctional imidazoles, electrophilic substitution on the preformed (trifluoromethyl)imidazole appears to be the method of choice in most cases. A large number of the products show herbicidal or insecticidal activity.
