| Abstract: | Cis,cis,cis-1,2,3,4-tetrakis(diphenylphosphinomethyl)cyclopentane:·1/2[PdCl(C3H5)]2 system catalyses the Suzuki cross-coupling of heteroaryl halides with a range of arylboronic acids with very high ratio substrate/catalyst in good yields. Substrates such as pyridines, quinolines, thiophenes, an indole, pyrimidines or a furane have been used successfully. |
