  • The Friedel–Crafts reaction is one of the most well-known methods available to organic chemists, but Friedel–Crafts methylation of arenes is generally not effective. Here, the authors use an HF/SbF5 superacid system to generate an arenium ion, which enables meta-selective methylation after a rearrangement.

  • The construction of four-membered rings via a 4-exo-dig cyclization was originally theorized to be unfavourable and only recently shown in sparse examples. Here the authors present a photochemical, radical 4-exo-dig cyclization of ynamides to form azetidines, promoted by copper photoredox catalysis.
