Hayakawa, Yoshio; Kimoto, Hiroshi; Cohen, Louis A.; Kirk, Kenneth L. published the artcile< Syntheses of (trifluoromethyl)imidazoles with additional electronegative substituents. An approach to receptor-activated affinity labels>, Quality Control of 112-63-0, the main research area is imidazole trifluoromethyl preparation herbicide insecticide; affinity label preparation trifluoromethylimidazole.
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 photochem. trifluoromethylation of the resp. 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.
