A Novel Ionic Liquid Based on Imidazolium Cation as an Efficient and Reusable Catalyst for the One-pot Synthesis of Benzoxazoles, Benzthiazoles, Benzimidazoles and 2-Arylsubstituted Benzimidazoles
A novel dicationic ionicliquid based on imidazolium cation is designed, synthesized and successfully used as catalyst for the one‐potsynthesis 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 ionicliquid. The application of this ionic liquid
