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.
A distinct approach for the synthesis of α-aminonitriles has been discovered by three-component reaction of nitroarenes, aldehydes, and TMSCN using indium in dilute aqueous HCl at room temperature. The products were formed in high yields (86–96%) within a short period of time (5–20 min). This one-pot conversion consists of the following steps: (i) reduction of nitro compounds to amines, (ii) formation
Nano magnetic sulfated zirconia (Fe<sub>3</sub>O<sub>4</sub>@ZrO<sub>2</sub>/SO<sub>4</sub><sup>2−</sup>): an efficient solid acid catalyst for the green synthesis of α-aminonitriles and imines
In this research, nano magnetic sulfated zirconia was prepared through a green and facile method and acted as a novel, heterogeneous, efficient nano-catalyst for the one-pot three component synthesis of α-aminonitrile derivatives.

this synthesis pathway, in situ polymerization onto the template surface led to the construction of a silica/polymer nanocomposite. Next, after removal of the template, the nanocomposite gels were transformed into mesoporous polysulfonamide nanospheres. After the physicochemical identification of the synthesized materials, functionalized polysulfonamides were used as reusable novelcatalysts with high

Then, it was used as a green nanocatalyst for the synthesis of α‐aminonitriles by a one‐potthree‐component condensation reaction of aldehydes or ketones, amines and trimethylsilylcyanide in ethanol at room temperature. The reaction procedure is simple, yields are very high, reaction
