catalytic system based on palladium-amido-N-heterocyclic carbenes for Suzuki–Miyauracouplingreactions of heteroaryl bromides is described. A variety of sterically bulky, amido-N-imidazoliumsalts were synthesized in high yields from the corresponding anilines. This catalytic system effectively promoted Suzuki–Miyauracouplings of heteroaryl bromides and chlorides with a range of boronic acids to
