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

Abstract

The direct copper-catalyzed <i>N</i>-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 <i>sec</i>-amines can also be tolerated well under this procedure
