2 -Phenylimidazoles, reaction with salts

A 25% yield of 2-phenylimidazole has been obtained136 by the action of ammonium carbonate in ethanol on l-benzoyl-2-cyanoaziri-dine (29) [from the reaction of a-chloro-j0-benzoylaminopropionitrile (30) with liquid ammonia]. Imidazolium salts have been isolated from... [Pg.131]

Electrophilic substitution reactions of 1-phenylimidazoles frequently involve substitution on the benzene rihg. When 1-phenylimidazole is nitrated with a mixed nitric-sulfuric acid reagent the major product is l-(p-nitrophenyl)imidazole. Such nitration has been shown to involve the imidazolium species as substrate. Nitration in acetic anhydride yields only the nitrate salt. [Pg.449]
