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

The cis,cis,cis-1,2,3,4-tetrakis(diphenylphosphinomethyl)cyclopentane/[PdCl(C3H5)]2 system catalyses the Suzuki cross-coupling of heteroaryl bromides with arylboronicacids with a very high substrate/catalyst ratio in good yields. Substrates such as pyridines, quinolines, thiophenes, an indole, a pyrimidine or a furane have been used successfully.
