The reaction of N‐methylimidazole (N‐MeIm) and N‐butylimidazole (N‐BuIm) with the complexes [PdCl2(PPh2py–P,N)] and [PdCl2(PPh2Etpy–P,N)] in the presence of NH4PF6 under N2 at room temperature afforded four new cationic Pd(II) complexes [PdCl(PPh2py–P,N)(N‐MeIm)](PF6) (1), [PdCl(PPh2py–P,N)(N‐BuIm)](PF6) (2), [PdCl(PPh2Etpy–P,N)(N‐MeIm)](PF6) (4) and [PdCl(PPh2Etpy‐P,N)(N‐BuIm)](PF6) (5) in good yields, where PPh2py is 2‐(diphenylphosphino)pyridine and PPh2Etpy is 2‐{2‐(diphenylphosphino)ethyl}pyridine). The complexes were fully characterized. The catalytic activities of these complexes were investigated for Suzuki–Miyaura cross‐coupling reactions at room temperature. Complex 2 exhibited excellent activity compared to other analogs. Copyright © 2013 John Wiley & Sons, Ltd.

The catalytic activity of three acetanilide palladacycles derived from easily accessible and commercially available acetanilide derivatives, viz. N-phenylacetamide (L1), N-(4-chlorophenyl)acetamide (L2) and N-(4-methylphenyl)acetamide (L3) has been examined in Pd-catalyzed Suzuki-Miyaura reaction of arylboronic acid with aryl bromides at room temperature. The complex 1L3 exhibited efficient activity in the Suzuki-Miyaura reaction (up to 99% isolated yield) under mild reaction conditions.
