Four functionalized bis(benzimidazolium) salts (2a-d) have been prepared and characterized by conventional spectroscopic methods and elemental analyses. A highly effective, easy to handle, and environmentally bengin process for palladium-mediated Suzuki cross-coupling was developed. The in situ prepared three-component system Pd(OAc)(2)/bis(benzimidazolium) bromides (2a-d) and Cs2CO3 catalyzes quantitatively the Suzuki cross-coupling of deactivated aryl chloride in aqueous media.
