✦ Synopsis

Abstract

By carefully choosing the right substrate ratio, catalyst combination, and base, symmetrical and unsymmetrical biaryls can be readily synthesized through the Pd‐catalyzed decarboxylative homo‐ and heterocoupling of substituted benzoic acids. The reaction gave the desired products in 40–90 % yield and is compatible with 2‐nitro‐, 2‐methoxy‐, 2‐fluoro‐, and 2‐chloro‐substituted benzoic acids.
