Synthesis of Biaryls <i>via</i> Ligand‐Free Suzuki–Miyaura Cross‐Coupling Reactions: A Review of Homogeneous and Heterogeneous Catalytic Developments

Abstract This review describes the recent developments in the field of Suzuki–Miyaura cross‐coupling reaction, in particular with regard to ligand‐free catalysis. The catalysts outlined here allow convenient and green synthetic pathways specifically for the construction of C–C bonds. They enable the synthesis of biaryls by the coupling arylboronic acids with aryl halides. The literature reporting ligand‐free synthesis of biaryls from 2010 to May 2015 has been reviewed. magnified image
