  • The concept of umpolung describes the reversal of the naturally occurring electrostatic polarization of chemical groups. It has now been used to make single mirror-image isomers of nitrogen-containing molecules. See Letter p.445

  • Chemical methods for adding carbon-based or nitrogen-based functional groups to alkenes are well established, but strategies for adding both to the same double bond have limitations; here, a method for the carboamination of alkenes at the same double bond is described.

  • Advances in photoredox catalysis have led to considerable developments in organic chemistry and its applied subfields. We discuss the development of low-energy light-absorbing photocatalysts and their use in synthesis, polymer chemistry, and biology.

  • Photoredox transformations are achieved with infrared light by using triplet fusion upconversion that converts infrared into visible light, enabling the use of photoredox chemistry on larger scales and through barriers that are impenetrable by visible light.

  • Technologies for profiling biological environments with high spatiotemporal resolution are in demand to enable the discovery of new targets for addressing unmet clinical needs. Now, a deep red light-mediated photocatalytic strategy for the targeted activation of aryl azides has been developed. This platform enables mapping of protein microenvironments in physiologically relevant systems.

  • A new compatibilization strategy installs dynamic crosslinkers into several classes of binary, ternary and postconsumer immiscible polymer mixtures in situ, with the resulting compatibilized dynamic thermosets exhibiting intrinsic reprocessability and enhanced tensile strength and creep resistance.

  • Site-selective functionalization of nearly identical C–H bonds has been a long-standing challenge. Now, a regioselective C–H amination has been achieved by [CpxIr(iii)] catalysis, which senses subtle electronic differences of allylic C–H bonds induced by remote electron-withdrawing groups. A linear correlation between Δ1JCH and ΔΔG‡ is found, leading to predictable regioselectivities.

  • CO2 can be used as an activator for the direct transformation of abundant and unprotected primary aliphatic amines into valuable γ-lactams under photoredox and hydrogen-atom-transfer catalysis. Electrostatic interactions between the in situ generated alkylammonium carbamate and the positively charged quinuclidinium radical lead to regioselective hydrogen atom abstraction.
