A simple and efficient method has been developed for the synthesis of α-aminonitriles by a one-pot three-component condensation of aldehydes, amines, and trimethylsilyl cyanide in the presence of a catalytic amount of silicasulfuricacid at room temperature. The silicasulfuricacid is reusable and could be applied in subsequent reactions with comparable activity.

A novel, simple and efficient one-pot synthesis of α-aminonitriles has been achieved by a three-component condensation of carbonyl compounds, amines and trimethylsilyl cyanide in the presence of (bromodimethyl)sulfoniumbromide as a catalyst at room temperature. The products were obtained in high yields and in short reaction times.

An efficient, mild and environmentally friendly method has been developed for the Streckerreaction to synthesize α-aminonitriles in the presence of K2PdCl4 as a catalyst. The three-component one-pot condensation of an aldehyde, amine and trimethylsilyl cyanide proceeded smoothly in water to afford the corresponding product in high yield with short reaction times.

Four novel magneticnanoparticlecatalysts with urea or urethane moieties are reported. The silica‐coated magneticnanoparticles 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

In the absence of catalysts, the three-component, one-pot synthesis of α-aminonitriles proceeded using various aldehydes and ketones together with amines and trimethylsilyl cyanide (TMSCN) in high yields under neat conditions at room temperature. The addition order of the reagents had a significant influence on the yields of the desired α-aminonitriles. In contrast, when tin ion-exchanged montmorillonite
