A new functionalized N‐heterocyclic carbene Pd II complex, [1,1′‐(hexylene‐1,6‐diyl)bis(3‐ n ‐butylbenzimidazol‐2‐ylidene)][PdCl 2 (CH 3 CN)] 2 ( 2 ) has been synthesized by reaction of NHC‐Ag transmetalation reagent with PdCl 2 (CH 3 CN) 2 . The molecular structure of 2 adopts an open conformation. Complex 2 was tested as a catalyst for Suzuki–Miyaura couplings of aryl halides with arylboronic acids in water and air. The results of these efforts show that 2 is an efficient precatalyst for such reactions. In addition, 2 is a good catalyst in Heck–Mizoroki reactions of aryl bromides with styrene.
