摘要:
An efficient protocol for ligand-free Cu-catalyzed N-arylation of heteroarylamines has been developed. With the use of 1% CuI, a wide range of aryl iodides and bromides coupled with heteroarylamines to afford the corresponding products in high yields. Further, this protocol is particularly suitable for reactions of the most hindered aryl iodides with 2-aminopyridines. (C) 2014 Elsevier Ltd. All rights reserved.
