The in situ prepared three component system Pd(OAc) 2 , 1,3‐dialkylbenzimidazolium halides ( 1a‐e ) and t ‐BuOK catalyses quantitatively the Suzuki cross‐coupling of deactivated aryl chloride substrates. 1,3‐Dialkylbenzimidazolium salts ( 1a‐e ) were characterized by conventional spectroscopic methods and elemental analyses.
