  • The synthesis of polycarbonyl compounds featuring four or more carbonyl groups is a synthetic challenge for organic chemists. Here, the authors describe how unsymmetric polycarbonyl compounds bearing up to 4 adjacent carbonyl groups can be accessed within a two-step synthesis from readily available starting materials and discuss their reactivity.

  • Gaining in-depth understanding of photochemical processes is key for developing more sustainable and efficient chemical transformations. Here the authors show that under visible light photochemical conditions, iminoiodinanes undergo formation of triplet nitrenes or nitrene radical anions, depending on the use of a photosensitizer; These reagents are studied in amination reactions with olefins.

  • A combination of an iron(ii)-catalyst and a hydroxylammonium salt enables the direct and selective conversion of an inert aromatic C–H bond to a valuable, unprotected amine functionality. This approach solves a long standing challenge in modern synthesis.

  • Diazoolefins are long-sought-after compounds, but experimental evidence for them is limited because of their high reactivity. Now, it has been shown that the reaction of N-heterocyclic olefins with nitrous oxide provides access to diazoolefins, enabling structural characterization and applications in organometallic and synthetic chemistry.
