Abstract A three‐component reaction between aliphatic or aromatic aldehyde, an amine and trimethylsilyl cyanide mediated by solid LiClO4, gave amino nitriles in good to excellent yields. The reaction proceeded smoothly under solvent‐free conditions without any side products.
The Strecker reaction was performed via a one-pot three component condensation of hetero aromatic/aromatic aldehydes, secondary amines and trimetylsilyl cyanide in the presence of propylphosphonicanhydride (T3P®) to accomplish the corresponding α-aminonitriles. The main advantages of this method are very short reaction time and excellent yields.
