A series of bulky amine palladium complexes [(Ar-NH2)2PdCl2]} were synthesized and characterized. The catalytic activity of the palladium complexes was evaluated via the direct C–H arylation of thiazoles with aryl bromides in aerobic conditions at 80–100 °C. Under the optimal conditions, 0.5–0.05 mol% of the bulky palladium complexes were found to be very efficient and produced the desired cross-coupling
