A novel dicationic ionic liquid based on imidazolium cation is designed, synthesized and successfully used as catalyst for the one‐pot synthesis of benzoxazoles, benzthiazoles, benzimidazoles and 2‐arylsubstituted benzimidazoles. The remarkable feature of this new catalyst is its ethyleneoxy bridge which participates in dissolving organic compound in ionic liquid. The application of this ionic liquid is studied in a new one‐pot method for synthesis of heterocyclic compounds under solvent‐free conditions. Simple and convenient procedure, high conversion, reusability of catalyst, easy purification and shorter reaction time are the advantageous features of this method.
