In the present paper it is described the use of hexamethylenetetramine combined to the use of bmim+ type ionic liquids as cheap, environmentally friendly and efficient catalytic systems for Baylis- Hillman reactions between aromatic aldehydes and acrylonitrile or methyl acrylate. The Baylis-Hillman adducts were obtained in moderate to good yields (50-85%), in short reaction times. The ionic liquids can be recycled.
