2-a]pyridines in high to moderate yields by microwave direct palladium-catalyzed C-H alkenylation between bromoalkenes and imidazo[1,2-a]pyridines. The scope and limitation of the palladium(0)-catalyzed alkenylation method were investigated. Optimized conditions were successfully applied to a wide variety of imidazo[1,2-a]pyridine derivatives and bromoalkenes. The compatibility of the synthesis with
