Propylamine modified with imidazolium ionic moiety grafted onto magnetic nanoparticles (MNPs) was prepared and evaluated as a catalyst for Knoevenagel condensation in water at room temperature. The catalyst was efficient in the reaction to give the condensation products in good yields. It is worth noting that the ionic-tagged catalyst performed significantly better than its ionic tag-free counterpart. Finally, the catalyst could be reused for 8 times with a slight loss in its catalytic activity. the Partner Organisations 2014.

The Knoevenagel condensation of aromatic aldehydes with active methylene compounds such as malononitrile, ethyl cyanoacetate, benzimidazole-2- acetonitrile and benzothiazole-2-acetonitrile proceeded very smoothly, in a reusable and cheap choline chloride and urea based deep eutectic solvents. Both reaction time and yield are satisfactory. The advantages of this catalyst are that it is readily available, biodegradable, non-toxic, low cost and is recyclable.
