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

A highly efficient, one-pot, three-component, solvent-free protocol for the synthesis of alpha-aminonitriles starting from their corresponding carbonyl compounds, amines, using Mitsunobu's reagent has been developed. Diversity of alpha-aminonitriles has been synthesized in good to excellent yields (80-99%) using various kinds of aldehydes/ketones and a variety of amines. (C) 2012 Elsevier Ltd.

A Novel Approach to the Synthesis of α-Aminonitriles Using Triphenyl- phosphine Dibromide under Solvent-Free Conditions
A quick and highly efficient, one-pot, three-component, solvent-free method for the synthesis of α-aminonitriles starting from the corresponding carbonyl compounds, amines, and trimethylisocyanide using triphenylphosphine dibromide, has been developed. Diverse α-aminonitriles have been synthesized in good to excellent yields (80–99%) using a range of aldehydes, ketones and amines.
