| Abstract: | Without any catalyst, a direct one-step synthesis of various benzimidazoles in methanol from aromatic aldehydes and 1,2-phenylenediamine was described using air as the oxidant. All reactions acquired good yield (≥69%), and the structures of all products were characterized by elemental analysis, IR and 1H MNR spectra. Compared to the previous methods, this new protocol has the advantages of simple procedure, mild conditions, easy purification and environment friendliness. |
