A novel approach to the synthesis of 2-carboxamide-substituted benzimidazoles from a wide range of 1,2-diamines and 2-functionalized acetamides was developed via elemental sulfur promoted cascade reaction. This procedure provides an efficient and facile route to benzimidazoles from readily available substrates under mild reaction conditions. The protocol is distinguished by efficiency in water and good tolerance to functional groups.
