Copper-Catalyzed <i>N</i>-Cyanation of Sulfoximines by AIBN

Abstract

The direct copper-catalyzed N-cyanation of sulfoximines was achieved by using AIBN as a safe cyanide source. It represents a simple and environmentally benign procedure for the construction of the N-CN bond. Furthermore, some sec-amines can also be tolerated well under this procedure.
