The cis,cis,cis-1,2,3,4-tetrakis(diphenylphosphinomethyl)cyclopentane/[PdCl(C3H5)]2 system catalyses the Suzuki cross-coupling of heteroaryl bromides with arylboronic acids 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.
