A General Method for the Suzuki−Miyaura Cross-Coupling of Sterically Hindered Aryl Chlorides:  Synthesis of Di- and Tri-ortho-substituted Biaryls in 2-Propanol at Room Temperature

The catalytic formation of di- and trisubstituted ortho biaryl junctions has been achieved using a palladacylce pre-catalyst bearing a N-heterocyclic carbene ligand. This transformation is performed at room temperature in technical grade 2-propanol.
