A simple, efficient, and cost-effective method has been developed for the one-pot, three-component condensationreaction of trimethylsilyl cyanide, aldehydes and aromatic amines using boricacid as a heterogeneous solid acid catalyst, under solvent-free conditions. α-Aminonitriles were synthesised relatively quickly in good yields at room temperature.
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

Silica-bonded S-sulfonic acid: an efficient and recyclable solid acid catalyst for the three-component synthesis of α-amino nitriles
Silica-bonded S-sulfonic acid (SBSSA) is employed as a recyclablecatalyst for the synthesis of α-amino nitriles. These syntheses were performed via a one-pot three-component condensation of aldehydes, amines, and trimethylsilyl cyanide under mild reaction conditions at room temperature.

Sodium dihydrogen phosphate was applied as an efficient and inexpensive catalyst for the synthesis of biologically potent α-aminonitrile derivatives through a one-pot three-component reaction of aldehyde, amine and trimethylsilyl cyanide. The reactions were easily carried out under mild, green and eco-friendly conditions in ethanol at room temperature affording high yields of the products in short times.
