Transition‐Metal‐Catalyzed Hydroarylation Reactions of Alkynes Through Direct Functionalization of C–H Bonds: A Convenient Tool for Organic Synthesis

Abstract

Abstract Direct functionalization of aromatic C–H bonds with alkynes provides an efficient synthetic protocol involving fewer reaction steps without need for prefunctionalization. This microreview presents an overview of the recently developed transition‐metal‐catalyzed hydroarylation reactions of alkynes. Special attention is paid to hydroarylation through alkyne activation processes and through arene activation processes.(© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2009)
