  • The functionalization of primary amines by C–H activation is often hindered by their strong metal-coordinating properties. Now, a steric tethering approach — which temporarily converts amino alcohols into hindered secondary amines — has been developed. The approach allows these amino alcohols to be transformed into structurally complex and diverse products using palladium-catalysed aliphatic C–H activation.

  • Oxatriquinane is a remarkably stable alkyl oxonium ion, despite the fact that its carbon–oxygen bond lengths are 1.54 Å. The robust nature of this fused tricyclic molecule enabled the addition of increasing steric bulk to the system, culminating in a tri-tert-butyloxatriquinane with a record 1.62 Å C–O bond distance.

  • Metal nanoparticles are widely used as heterogeneous catalysis, but the possibility of simultaneous homogeneous pathway via metal ion leaching also exists. Here, the authors use single-molecule spectroscopy to observe catalytic events directly on the surface of the nanoparticles, supporting a purely heterogeneous pathway.

  • Although the synthetic chemistry of carbon dioxide has generally been limited to two-electron pathways, single-electron mechanisms would open avenues to new reactivity. Now, the coupling of carbon dioxide and amines to produce α-amino acids can be achieved by an organic photoredox catalyst in continuous flow.
