New, sterically demanding 1,3‐dialkylbenzimidazolium salts ( 2a–c ) as N ‐heterocyclic‐carbene precursors have been synthesized and characterized. The ortho position of aromatic aldehydes was directly and selectively arylated with aryl chlorides in the presence of a catalytic system prepared in situ from Pd(OAc) 2 , 1,3‐dialkylbenzimidazolium chlorides ( 2a–c ), and Cs 2 CO 3 . © 2008 Wiley Periodicals, Inc.
