Ionic liquids [Bmim]BF₄ and [Bpy]BF₄ were employed as environmentally benign media in Doebner condensation to synthesize α,β-unsaturated carboxylic acid. The good results showed that [Bmim]BF₄ and [Bpy]BF₄ were efficient media for Doebner condensation, which could be recycled easily. The highest yields could reach 93%and 90%in [Bmim]BF₄ and [Bpy]BF₄, respectively.
