  • Halogen-substituted silylium ions are compounds for which Lewis superacidity has been predicted, but their synthesis has proven challenging. Now a series of ionic halosilylium Lewis superacids have been prepared in the condensed phase, opening the door to their application in synthetic processes.

  • The occurrence of isomers of the bicyclic octapeptide α-amanitin, which presents a macrolactam with a tryptathionine cross-link forming a handle, has been reported under the term of atropoisomers. Here, the authors synthesize its analogs and analyse their isomers, proposing and describing for them the term ansamer.

  • Neutral homoaromatic hydrocarbons—which possess an interrupted π-system yet display aromatic properties owing to through-space or through-bond interactions—have remained rare as they are typically unstable. Now a class of stable neutral homoaromatic homoannulenes has been synthesized, including one that acts as a photoswitch through a reversible [1, 11] sigmatropic rearrangement.

  • As the structure of bulk aluminium chalcogenides is composed of three dimensional networks their molecular congeners exhibit a strong tendency to oligomerize. Here, the authors describe the isolation of a monotopic aluminium telluride and probe its structural and bonding characteristics.
