Metal-Free Reductive Amination of Aldehydes for the Synthesis of Secondary andTertiary Amines. -Secondary and tertiary aromatic amines are synthesized by metal-free one-pot reductive amination of various aldehydes with primary aromatic amines using benzaldehyde/o-phenylenediamine as reducing system. Pharmaceutically interesting benzimidazole is obtained as by-product and can be easily recovered from the reaction mixture by filtration. -(AMBICA; KHAJURIA, R.; SAINI, Y.; KAPOOR*, K. K.; Indian J.
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.
