Özet
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 (\textbf{3}) were fully characterized by elemental analysis and $^{1}$H and $^{13}$C 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.
