The bases 2-(2'-pyridyl)imidazole and 2-(6'-methyl-2'-pyridyl)imidazole have been synthesized and shown to be capable of functioning as bidentate chelating agents. The cations of certain of the complex salts they and 2-(2 '-pyridyl)benzimidazole form with transition metal salts can be deprotonated with bases to "neutral" complexes. However, it has not proved possible by treatment with alkalies to deprotonate such salts so as to obtain complexed metal in the anions.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
