A copper-mediatedhalotrifluoromethylation of unactivatedalkenes using Umemoto’s reagent and copper(I) halide (CuX, X=Cl, Br, and I) was developed. The CuX species (CuI, CuBr, and CuCl) were chosen as the source for both copper and halides because of their benchtop stability, commercial availability, and relatively low cost. Simple exchange of the copper salt provided the desired simultaneous and
visible light have undergone a renaissance in recent years. Polypyridyl dyes such as Ir(ppy)3 and Ru(bpy)3 are key catalysts in this event, and blue‐ or white‐lightirradiation is required for the chemical transformations. However, it remains a challenge to achieve reactions under the lower energy of redlight. We disclose, herein, that trifluoroethoxy‐coatedsubphthalocyanine realizes the red‐light‐driven
