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
