Copper-catalyzed amination of aryl halides: single-step synthesis of triarylamines

A simple and efficient methodology for the synthesis of triarylamines in a single step has been demonstrated using a ligand-free CuI catalyst and potassium tertiary butoxide as the base. Use of chelating ligands leads to the formation of triarylamine derivatives selectively (95% yield) with high catalytic activity. (C) 2002 Published by Elsevier Science Ltd.
