An efficient system for the direct catalytic intermolecular α‐arylation of acetamide derivatives with aryl bromides and chlorides is presented. The palladium catalyst is supported by Kwong’s indole‐based phosphine ligand and provides monoarylated amides in up to 95% yield. Excellent chemoselectivities (>10:1) in the mono‐ and diarylation with aryl bromides were achieved by careful selection of bases

A general and efficient method for the synthesis of a wide range of amides is described here. The reactions were conducted under convenient conditions and provided secondary and tertiary amides in moderate to excellent yields. A variety of amines and substituted alkynyl bromides were used to investigate the scope of the reactions. (C) 2011 Elsevier Ltd. All rights reserved.

Strong competition: A method for the meta‐selectivearylation of the highly versatile α‐aryl carbonyl motif using diaryliodonium salts is described. In this CuII‐catalyzed process the remote carbonyl group is capable of overpowering even strongly para‐directing functionalities to form the elusive meta‐products (see scheme). Remarkably, the arylation process can also operate under metal‐free conditions
