Based on the strategy of the development of phosphine-free palladium-catalyzeddirect C–H arylation, a series of camphyl-based α-diimine palladium complexes bearing sterically bulky substituents were synthesized and characterized. The palladium complexes were applied for the cross-coupling of thiazole derivatives with arylbromides. The effect of the sterically bulky substituent on the N-aryl moiety
