摘要：

The easily available and efficient catalyst containing a benzimidazolium ligand and PdCl2(PPh3)(2) demonstrated excellent catalytic activity to construct the flavones and aurones, respectively. This reaction can be operated under mild conditions, affording the desired products in moderate to good yields. This protocol was used to prepare the flavones and aurones by a slight modification of amines. (C) 2013 Elsevier Ltd. All rights reserved.
