2-(1H-Benzo[d] imidazol-2-yl)-3-arylacrylonitrile derivatives not only exhibit a variety of important biological activities, but also are important intermediates in organic synthesis. The CBr4-promoted reaction of aromatic aldehydes with 2-(1H-benzo[d] imidazol-2-yl) acetonitrile to obtain 2-(1H-benzo[d] imidazol-2-yl)-3-arylacrylonitriles was developed. Structurally diverse 2-(1H-benzo[d] imidazol-2-yl)-3-arylacrylonitriles were obtained in moderate to good yields (74%~96%) under mild conditions. This method has the advantages of operational simplicity and wide substrate scope.
