Novel five-membered (kappa(2) - C, N)-palladacyclic complexes were prepared from the reaction of the corresponding acetate-bridged palladacycle dimer with N-heterocyclic carbene (NHC) ligands in high yields. Palladacyclic complexes (3) were fully characterized by elemental analysis and H-1 and C-13 NMR spectroscopy. Palladacyclic complexes were tested as catalyst for the C C bond forming reaction. These complexes were found to be efficient catalysts for the Suzuki-Miyaura reaction of aryl bromides.
