Abstract

Reaction of aromatic aldehyde, 5,5-dimethyl-1,3-cyclohexanedione and p-toluidine in water were successfully carried out in the presence of p-dodecylbenezenesulfonic acid (DBSA) as a Brφnsted acid-surfactant-combined catalyst. This method provides several advantages such as environment friendliness, high yields and simple work-up procedure. In addition, water was chosen as a green solvent.
