Description
Summary:A room temperature protocol for the coupling between aryldiazoacetates and boronic acids is described, exhibiting limited scope in the dark, but being significantly improved under blue‐light irradiation. An intricate mechanistic scenario reveals common aspects for both processes, both relying on the generation of a key carbene intermediate, which attacks the boronic acid partner. These features are represented in the illustration by the yin yang symbol and the starships. More information can be found in the Full Paper by I. D. Jurberg et al. on page 5648.
