blue light irradiation (460 nm) was key to promote the desired transformation while generating benign wastes. Mechanistic studies suggest the formation of a N-chloro species that undergoes selective coupling via a radical pathway induced by the combination of light and oxygen. Further development led to an optimized semi-batch process, which was successfully scaled up to an initial 20 L and then 1.2 m3
