An efficient one-pot procedure for the synthesis of 2-aminobenzimidazoles from isoselenocyanates and various substituted diamines is described. Precipitation of elemental selenium from the reaction mixture greatly simplifies the purification procedure and also allows it to be re-used for preparation of isoselenocyanates. A possible mechanism for the formation of 2-aminobenzimidazoles is proposed.
of 2‐(anilino or 2,6‐dichloroanilino)‐1,5(6)‐disubstituted‐1H‐benzimidazoles (1–43) were prepared by reaction of several 2‐chloro‐ or 2‐chloromethyl‐1H‐benzimidazoles with aniline derivatives. The prepared compounds were screened for their in vitro antibacterial and antifungal activities. Compounds 2, 8, and 9 exhibited the best activity.
