γ-Al2O3-Supported 12-Tungstosilicic Acid as an Efficient Heterogeneous Catalyst for the Synthesis of α-Aminonitrile
摘要:
The multicomponent Strecker reaction using trimethylsilyle cyanide was performed in very short reaction times, and alpha-aminonitriles were prepared in excellent yields in the presence of a catalytic amount of alumina-supported tungstosilicic acid.

Abstract One‐step synthesis of α‐aminonitriles was successfully carried out by a three‐component condensation of aldehydes or ketones, amines, and potassium cyanide in the presence of a catalytic amount of K5CoW12O40·3H2O as an efficient, reusable, and nontoxic catalyst.

A simple and general method has been developed for the synthesis of α-aminonitriles by a one-pot three-component condensation of aldehydes or ketones, amines and potassium cyanide in THF in presence of a catalytic amount of indium trichloride.
The multicomponent Strecker reaction using trimethylsilyle cyanide was performed in very short reaction times, and alpha-aminonitriles were prepared in excellent yields in the presence of a catalytic amount of alumina-supported tungstosilicic acid.
