Four novel magnetic nanoparticle catalysts with urea or urethane moieties are reported. The silica-coated magnetic nanoparticles were simply functionalized via addition of 3-(triethoxysilyl)propylisocyanate (TESPIC), amine or amino alcohol. TESPIC with dual labile functional groups was used as a suitable precursor for the synthesis of urethane-based catalysts. The newly synthesized catalysts were fully characterized using a variety of techniques. These functionalized magnetic nanoparticles were used as reusable catalysts in the Strecker synthesis of α-aminonitrile derivatives under solvent-free conditions at 50?°C.

Fe3O4 magnetic nanoparticle-supported BF3 was prepared as a new magnetically separable Lewis acid catalyst and successfully used for the one-pot synthesis of α-aminonitriles. A broad range of substrates including the aromatic and heteroaromatic aldehydes, cyclic ketones (cyclopentanone, cyclohexanone and cycloheptanone), aryl-alkyl ketones, diaryl ketones and tetralones, isatin derivatives and acenaphthenequinone were condensed with amines (aliphatic and aromatic) and trimethylsilyl cyanide. All reactions were completed in short times and products were obtained in good to excellent yields. The catalyst could be recycled and reused several times without any loss of efficiency. Finally, α-aminonitrile containing adenine was successfully synthesized.

A three-component, Strecker reaction of a series of aldehydes or ketones, amines, and trimethylsilyl cyanide for the synthesis of α-aminonitriles in the presence of a catalytic amount of a magnetic solid sulfonic acid catalyst, Fe3O4@SiO2@Me&Et-PhSO3H under solvent-free conditions have been investigated. This catalyst, with a combination of hydrophobicity and acidity on the Fe3O 4@SiO2 core-shell of the magnetic nanobeads, as well as its water-resistant property, enabled easy mass transfer and catalytic activity in the Strecker reaction. The catalyst was easily separated by an external magnet and the recovered catalyst was reused in 6 successive reaction cycles without any significant loss of activity.
