A new method of synthesis of some 2‐aryl and 2‐heterocyclic benzimidazole, benzoxazole and benzothiazole derivatives

Abstract A new one‐step facile method for the synthesis of some benzimidazole, benzoxazole and benzothiazole derivatives is described. The method involves the action of aromatic and heterocyclic selenoamides on some o ‐phenylenediamine, o ‐aminophenol and o ‐aminothiophenol and their derivatives.
