An inexpensive cyclodiphosphazane as an efficient ligand for the palladium-catalyzed amination of aryl bromides and chlorides

Abstract

An economic and novel ligand, cyclodiphosphazane [ClPN(t-Bu)]2 (1), was introduced in the palladium-catalyzed amination of unactivated aryl halides. The catalyst allows for the amination of aryl chlorides and bromides with secondary cyclic amines and anilines in good yields. © 2009 Elsevier Ltd. All rights reserved.
