An efficient protocol for the ligand-free and heterogeneous Pd/C-catalyzed one-pot, three-componentsynthesis of aryl-substituted benzimidazoles from benzyl alcohols by using water as the solvent was developed. The reaction involves hydrogen-transfer and Suzuki reactions. This method is quite convenient and environmentally friendly.
A facile and convenient method for the synthesis of highlyfunctionalized2-(substitutedbiphenyl) based benzimidazoles has been reported by the application of Suzuki-Miyauracrosscouplingreaction.
