Exogenous photocatalyst-free, single nickel-catalyzed carbon–heteroatomcoupling under visible-light irradiation is reported. Over 15 classes of nucleophile can efficiently couple with aryl/alkene halides to afford valuable heteroatomic arenes/alkenes. The unprecedentedly broad substrate scope and late-stage modification of valuable molecules fully demonstrate the benefits of the method.
