  • Homochiral porous cage-in-cage structures that self-assemble from lanthanide cations and chiral amino acid-derived ligands have been prepared and shown to be highly effective in enantioselective separations of small-molecule guests.

  • The supramolecular assembly of oligomers encoded with complementary recognition units enables duplex hybridization with helical structure.

  • Selective cross-coupling at either of two similar halide substituents in a dihalogenated substrate can be achieved by controlling the speciation of the active palladium catalyst.

  • It has so far proved difficult to characterize halogen bonds in solution. A new and simple approach is to use scalar coupling between atoms in a halogen bond donor as a measure of bond strengths with diverse acceptors.

  • Cementitious materials — not least their reinforcements — are prone to aerobic oxidation, followed by chloride and sulfate attack. These processes jeopardize structures, particularly those exposed to air and seawater.

  • Locally activating prodrugs through targeted irradiation — a new concept for concurrent chemotherapy and radiotherapy.

  • The Fenton and Fenton-like reactions feature in oxidative stress and are central to advanced oxidation technologies to remediate organic pollutants. The reactions are often simplistically taught to afford only hydroxyl radical as the active oxidant. Yet, this is just one of many possible oxidants and is probably not the major oxidant formed under biological conditions.

  • A polymer coating made from cosmetics-based ingredients can be applied to diverse surfaces to capture airborne droplets and mitigate the transmission of infectious respiratory diseases.

  • A disilagermirene is a cyclopropene analogue with an unsaturated Si=Ge moiety. Such rings can be generated and stabilized in the presence of Ni, which the Si=Ge group binds through its σ-bond rather than π-bond.

  • Laser ablation enables the study of discrete metal difluorides and their reactions with dioxygen and ozone. Metal-fluoride vibrational energies give an indication of the charge on a metal difluoride moiety and help us rationalize the resultant structures.

  • An experiment that challenged established dogma opened an entirely new avenue for research in the assembly and control of mechanically interlocked compounds.

  • A range of aryl and alkenyl organosodium reagents can be prepared by halogen–sodium exchange reactions with neopentylsodium and may be a useful alternative to widely used organolithium reagents.

  • As scientists of all stripes grow as leaders, it becomes their responsibility to shed light on the opportunities that may be hidden within an apparent failure. Presented as a letter to his younger self, Marc Reid looks back at the time when he could scarcely handle professional rejection and examines the lessons he learned.

  • Gold(III) complexes can undergo facile reductive elimination of aryl halides, particularly when bulky co-ligands are present. This study informs us about the elementary reactions of copper(III) congeners, which are prominent intermediates in organic cross-couplings.
