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
