Nickel-catalyzed transamidation of aliphatic amide derivatives. [PDF]
, 2017 Transamidation, or the conversion of one amide to another, is a long-standing challenge in organic synthesis. Although notable progress has been made in the transamidation of primary amides, the transamidation of secondary amides has remained ...

A two-step approach to achieve secondary amide transamidation enabled by nickel catalysis. [PDF]
, 2016 A long-standing challenge in synthetic chemistry is the development of the transamidation reaction. This process, which involves the conversion of one amide to another, is typically plagued by unfavourable kinetic and thermodynamic factors. Although some

Intermolecular interactions in N-(ferrocenylmethyl)anthracene-9-carboxamide [PDF]
, 2003 The title compound, [Fe(C₅H₅)(C₂₁H₁₆NO)], was synthesized from the coupling reaction of anthracene-9-carboxylic acid and ferrocenylmethylamine. The ferrocenyl (Fc) group and the anthracene ring system both lie approximately orthogonal to the amide moiety.
