An advanced novel magnetic ionic liquid based on imidazolium tagged with ferrocene, a supported ionic liquid, is introduced as a recyclable heterogeneous catalyst. Catalytic activity of the novel nanocatalyst was investigated in one-pot three-component reactions of various aldehydes, malononitrile and 2-naphthol for the facile synthesis of 2-amino-3-cyano-4H-pyran derivatives under solventfree conditions without additional co-catalyst or additive in air. For this purpose, we firstly synthesized and investigated 1-(4-ferrocenylbutyl)-3- . The synthesized novel catalyst was characterized using 1 H NMR, 13 C NMR, Fourier transform infrared and energy-dispersive X-ray spectroscopies, X-ray diffraction, and transmission and field emission scanning electron microscopies. Combination of some unique characteristics of ferrocene and the supported ionic liquid developed the catalytic activity in a simple, efficient, green and eco-friendly protocol. The catalyst could be reused several times without loss of activity.

A variety of organocatalysts has been screened for the synthesis of arylaminonaphthols. It has been shown that (N,N-dimethylethanolamine) is a highly efficient organocatalyst for the direct synthesis of a novel class of arylaminonaphthols via three-component condensation of 2-naphthol, aldehydes, and arylamines under solvent-free conditions. Mild, one-pot, and green reaction conditions, relatively short reaction times and good yields make this protocol highly significant. 25 new compounds have been synthesized by this method.
