Abstract

This paper reports an efficient synthesis of 4-heteroaryl-substituted triphenylamine derivatives via the palladium-catalyzed Suzuki reaction of heteroaryl halides with 4-(diphenylamino)phenylboronic acid in ethylene glycol under ligand-free and aerobic conditions. These derivatives are important structural motifs for use in dye-sensitized solar cells and organic electroluminescence materials. Copyright © 2011 John Wiley & Sons, Ltd.
