Abstract

This highlight provides a general overview of Cα–H oxidations of amines to form amides. Initial as well as recent examples are reviewed with a particular focus on existing challenges regarding substrate scope and reaction conditions. Finally, one very recently established catalyst system is described in detail which achieves the iron-catalyzed, Cα–H oxidation of amines under mild conditions.
