Copper‐Catalyzed Efficient Dithiocyanation of Styrenes: Synthesis of Dithiocyanates.

ABSTRACTA novel Cu-catalyzed intermolecular chemoselectivity dithiocyanation of styrenes with ammonium thiocyanate has been developed under mild conditions. This reaction exhibits a wide range of functional-group tolerance in styrenes to afford various dithiocyanates. The reaction mechanism was primarily investigated and a radical process was proposed.
