Using a Pd/Ag bimetallic system, arylations of simple arenes with perfluorobenzoic acids have been achieved by decarboxylative C-H bond functionalization, providing the desired cross-coupling products in moderate to good yields. These straightforward protocols provide new and efficient methods for the synthesis of fluorobiphenyl scaffolds under simple and mild conditions. (C) 2013 Elsevier Ltd. All rights reserved.
Gold-Catalyzed Direct Oxidative Arylation with Boron Coupling Partners
An efficient synthesis of biaryls through a gold‐catalyzed oxidative cross‐coupling of arenes with strong electron‐deprived aryl boronates is presented herein. Regio‐ and chemocontrol are achieved by the selective activation of these coupling partners by gold at different oxidation states. Under reaction conditions devoid of basic additives or directinggroups, the role of acetato ligand as an internal
