Aryl imines, formed in situ from aldehydes and amines undergo mild nucleophilic addition with trimethylsilyl cyanide on the surface of montmorillonite KSF clay to afford the corresponding α-aminonitriles in excellent yields. The solid acid can be recovered and recycled in subsequent reactions with a gradual decrease of activity.
