Abstract
A versatile microwave-assisted procedure for the palladium-catalyzed direct arylation of heterocycles by aryl bromides and heteroaryl bromides features short coupling times (10-60 min) and low catalyst loadings and allows the successful arylation of previously unreactive heterocyclic substrates.
