A highly efficient and general method for Suzuki cross-coupling reaction en route to the synthesis of polycyclicaromatic hydrocarbons (PAHs) and their metabolites has beendeveloped. Microwave irradiation of aryl bromides 1 andboronic acids (2 and 3) using polyurea microencapsulatedpalladium catalyst (Pd EnCat 30) gave the coupling adducts4 and 5 in excellent yields in just 20 min compared to ∼24h under thermal conditions, corresponding to a ∼72-foldincrease in reaction rate.
