Abstract

In this study, functionalized 2-(trichloromethyl)-1-benzo[]imidazole derivative with good yields was synthesized using a copper-catalyzed -arylation reaction of 2-iodoaniline and trichloroacetonitrile. This reaction was performed by employing the catalytic value of copper (I) and 1,10-phenanthroline as the ligand in tetrahydrofuran solvent at 23°C. In the following, the reaction of the final product with phenylacetylene and sodium azide (Huisgen reaction) using the copper catalyst in water solvent at 23°C led to the synthesis of new (1,2,3-triazol)-1-benzo[]imidazole derivatives with the principles of green chemistry and suitable efficiency. The availability of raw materials and suitable catalysts, mild reaction conditions, and easy purification are among the advantages of this method for the synthesis of various multi-substituted benzo[]imidazole and 1,2,3-triazole derivatives.
