sp 3 C–H bonds with comparable properties. If the intermediate radical could be further trapped enantioselectively, this should enable highly site- and enantioselective functionalization of C–H bonds. Here we report a copper (Cu)-catalysed site- and enantioselective allylic C–H cyanation of complexalkenes, in which a Cu(ii)-bound nitrogen (N)-centred radical plays the key role in achieving precise site-specific
