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.
