Unexpected side reactions of imidazolium-based ionic liquids in the base-catalysed Baylis-Hillman reaction

Low yields are obtained when the Baylis-Hillman reaction is conducted in the presence of an imidazolium-based ionic liquid due to direct addition of the deprotonated imidazolium salt to the aldehyde. Ionic liquids are evidently not inert.
