Microwave-accelerated iridium-catalyzed borylation of aromatic C-H bonds.

Microwave heating accelerates the Ir-catalyzed C-H borylation of aromatic substrates when compared with reactions carried out at the same temperature under standard heating conditions. Application to a one-pot single solvent process for tandem C-H borylation/Suzuki-Miyaura cross-coupling sequences using microwave-accelerated reactions gives fast and efficient access to a wide range of biaryl and heterobiaryl compounds.
