These eight Pd-NHC complexes are as follows: bis[1-phenyl-3-(2,4,6-trimethylbenzyl)benzimidazol-2-ylidene]dichloropalladium(II), bis[1-phenyl-3-(2,3,5,6-tetramethylbenzyl)benzimidazol-2-ylidene]dichloropalladium(II), bis[1-phenyl-3-(2,3,4,5,6-pentamethylbenzyl)benzimidazol-2-ylidene]dichloropalladium(II), bis[1-phenyl-3-(3,4,5-trimethoxybenzyl)benzimidazol-2-ylidene]dichloropalladium(II), bis[1-(2-diethylaminoethyl)-3-(3-methylbenzyl)benzimidazol-2-ylidene]dichloropalladium(II), bis[1-(2-diethylaminoethyl)-3-(2,3,5,6-tetramethylbenzyl)benzimidazol-2-ylidene]dichloropalladium(II),bis[1-(2-morpholinoethyl)-3-naphthalenomethylbenzimidazol-2-ylidene]dichloropalladium(II) and bis[1-(2-morpholinoethyl)-3-(2-methylbenzyl)benzimidazol-2-ylidene]dichloropalladium(II). Also, these synthesized complexes were fully characterized using Fourier transform infrared, H-1 NMR and C-13 NMR spectroscopic methods and elemental analysis techniques. These synthesized novel Pd-NHC complexes were tested as catalysts in the direct arylation of 2-n-butylthiophene, 2-n-butylfuran and 2-isopropylthiazole with various aryl bromides at 130 degrees C for 1 h. The complexes showed very good catalytic activities in these reactions.
