From readily available starting materials functionalized 1,3-dialkylbenzimidazolium salts (1a-g) have been prepared and characterized by conventional spectroscopic methods and elemental analysis. The in situ prepared three component system Pd(OAc)2/1,3- dialkylbenzimidazolium halides (1a-g) and Cs2CO3 catalyses Suzuki cross-coupling of aryl chloride substrates. These concepts for making catalysts in situ open the way for the discovery of many new catalysts via the interaction of commercially available metal complexes and suitable electron releasing ligands.
