Flash chemistry using flowmicroreactors enables highly chemoselective reactions of difunctional electrophiles with functionalized aryllithium compounds by virtue of extremelyfast micromixing. The approach serves as a powerful method for protecting‐group‐free synthesis using organolithium compounds and opens a new possibility in the synthesis of polyfunctional organic molecules.

A practical copper‐catalyzed direct nitration of protected anilines, by using one equivalent of nitric acid as the nitrating agent, has been developed. This procedure features mild reaction conditions, wide structural scope (with regard to both N‐protecting group and arene substitution), and high functional‐group tolerance. Dinitration with two equivalents of nitric acid is also feasible.
