Methanolic solutions of dodecacarbonyltriiron [Fe«(CO)i2] specifically reduce the nitro group of nitroaryls to a primary amine in the presence of functional groups often encountered in aromatic synthesis {e.g., C=C, C=0, COzR, NHAc). High yields result. The effective reducing agent is the hydridoundecacarbonyltriferrate anion. Aspects of the synthetic scope and mechanistic pathway are discussed.
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.
