Iron-promoted electrochemical trimerization for the synthesis of sterically hindered polysubstituted electron-deficient aromatic amines.

Abstract

An iron-promoted electrochemical C-H amination method has been developed for the one-step construction of sterically hindered amines from simple electron-deficient arylamines. This ligand-free approach enables direct access to trimeric amine frameworks under mild electrochemical conditions. Single-crystal analysis revealed their unusual connectivity, providing insights into complex amine structure formation.
