Organocatalytic activation of TMSCN by basic ammonium salts for efficient cyanation of aldehydes and imines

Basic ammonium salts act as highly effective catalysts for the cyanosilylation of aldehydes and in Strecker-type aminonitrile synthesis using TMSCN as cyanide source at 25 °C under extremely mild conditions, affording very good to excellent yields of silylated cyanohydrins and α-aminonitriles.
