A highly efficient and general method for Suzuki cross-couplingreaction en route to the synthesis of polycyclic aromatic hydrocarbons (PAHs) and their metabolites has been developed. Microwave irradiation of aryl bromides 1 and boronic acids (2 and 3) using polyurea microencapsulated palladium catalyst (Pd EnCat 30) gave the coupling adducts 4 and 5 in excellent yields in just 20 min compared to ∼24
