Cis,cis,cis-1,2,3,4-tetrakis(diphenylphosphinomethyl)-cyclo pentane/[PdCl(C3H5)]2 system catalyses the cross-coupling of aryl chlorides with arylboronic acids with high ratios substrate/catalyst. A turnover number of 6800000 has been obtained for the addition of the activated 2-chloro-5-(trifluoromethyl)nitobenzene to benzeneboronic acid in the presence of this catalyst.
