摘要：

An efficient copper catalyst system, Cu2O/beta-ketoimine L-1, for the N-arylation of nitrogen-containing heterocycles with aryl iodides and bromides has been developed. The system works well with the electron-rich, -neutral, and -deficient aryl bromides to afford the products in good to excellent yields. (C) 2008 Elsevier Ltd. All rights reserved.
