Abstract :Novel five-membered insert ignore into journalissuearticles values($\kappa ^{2}-C,N);$-palladacyclic complexes were prepared from the reaction of the corresponding acetate-bridged palladacycle dimer with N-heterocyclic carbene insert ignore into journalissuearticles values(NHC); ligands in high yields. Palladacyclic complexes insert ignore into journalissuearticles values(\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.
