Four functionalized bis(1,4,5,6-tetrahyropyrimidinium) salts (2a-d) have been prepared and characterized by conventional spectroscopic methods and elemental analyses. A highly effective, easy to handle and environmentally benign process for palladium mediated Suzuki cross-coupling was developed. The in situ prepared three component system Pd(OAC)(2) / bis(1,4,5,6-tetrahyropyrimidinium) bromides (2a-d) and CS2CO3 catalyses quantitatively the Suzuki cross-coupling of deactivated aryl chloride.
