2-Hydroxyethylammonium formate as a cost-effective and task-specific ionic liquid efficiently promotes the condensation of nitroalkanes with various aldehydes to produce β-nitrostyrenes in very good yields at room temperature. This reaction does not involve any hazardous organic solvent and toxic catalyst. The ionic liquid can be recovered and recycled for subsequent reactions.
