| Abstract: | A mixture of novel benzimidazole salts (2a–f), Pd(OAc)2 and K2CO3 in DMF? H2O catalyzes, in high yield, the Heck cross‐coupling reaction assisted by microwave irradiation in a short time. All synthesized novel benzimidazole derivatives were characterized by elemental analysis and NMR spectroscopy. In addition, the molecular structure of 2a was determined by X‐ray crystallography.
