✦ Synopsis

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.
