The classical nature of bromination of alkanes and photoredox chemistry is signified by the greyscale in the background photo. In contrast, the brighter choice of color highlights the renaissance of photoredox chemistry. In particular, Choon Hong Tan and co‐workers report a photoredox bromination which uses an organic dye as photoredox catalyst in their Full Paper on page 536 ff. Selective bromination of sclareolide and estrone derivatives was demonstrated. A radical relay to generate the CH‐abstracting species from morpholine was proposed through experimental and computational studies. Photo credit: Chan Ke Min.
