The direct arylation reaction has attracted attention in recent years especially because of its environment-friendly properties. In this study, we researched the synthesis of 2-hydroxyethyl substituted bis(NHC)Pd(II) complexes and also the synthesis of N-coordinate-Pd(II)(NHC) complexes containing N-bound benzimidazolium from palladium acetate ([Pd(CH3COO)(2)]) with 1,3-disubstituted benzimidazolium halides in DMSO. All the complexes have been characterized by using H-1 NMR, C-13 NMR, FTIR spectroscopy and elemental analysis techniques. The molecular and crystal structure of one of the complexes is confirmed by using single-crystal X-ray diffraction. These complexes have been examined as the catalyst in the direct arylation reaction with 2-n-butylfuran and 2-n-butylthiophene and have demonstrated excellent activity in this reaction.
