Abstract: The present work describes a new experimental protocol of the Morita-Baylis-Hillman reaction in H2O / Ionic Liquid media under microwave irradiation. Different proportions of ionic liquids, ([bmim][PF6] and [bmim][BF4]), and water were tested as solvents for the reaction between several aromatic aldehydes and Michael acceptors under microwave irradiation. The results show that small amounts of ionic liquid, mixed in water, can shorter reaction times keeping good yields.
