A straightforward, mild, efficient, one-pot method has been found for the synthesis of α-aminonitriles via three-component Strecker reaction using acetals or cyclic acetals, curious aromatic amines and trimethylsilyl cyanide (TMSCN) catalysed by hafnium tetrachloride at room temperature. It is with good to excellent yields under mild conditions. This developed approach has been successfully applied

Aqueous formic acid (37%) was effectively used as catalyst in Strecker reaction to afford α-aminonitriles and imines in high yields.
A concise, straightforward and efficient method has been developed for the synthesis of α-aminonitriles by an one-pot three-component condensation of aldehydes or ketones, amines and trimethylsilyl cyanide catalyzed by MgI2 etherate under solvent-free conditions. This protocol has some advantages such as mild reaction condition, simple work-up, short reaction time and high product yields.
