The first enantioselective copper-catalyzed cyanation of propargylic C–Hbonds via radical relay was established using novel BoxOTMS ligands, providing an efficient and straightforward tool for the construction of structurally diverse chiral allenyl nitriles in good yields with excellent enantioselectivities. This reaction features high functional group tolerance and mild conditions. In addition, the
