  • Photoredox-catalysed coupling of electron-rich aryl electrophiles based on simple nickel salts usually suffers from a slow oxidative addition. Now, it is shown that thianthrenation leads to more favourable redox properties of the substrates, alleviating this problem in carbon–heteroatom bond-forming reactions.

  • A study demonstrates that nitrous oxide can act as the source of O in a catalytic conversion of aryl halides to phenols, releasing N2 as by-product.

  • The use of main-group elements in radical cross-coupling reactions has been little explored. Now, a low-valency bismuth complex has been shown to emulate the behaviour of first-row transition metals and undergo single-electron-transfer oxidative addition to redox-active electrophiles, leading to the development of a bismuth-catalysed C–N coupling reaction between amines and carboxylic acids.

  • In cells, di-iron hydrogenases require three maturases to facilitate proper assembly of metal clusters. Reconstitution experiments with synthetic cofactor mimics coupled with functional and spectroscopic characterization now show these helper proteins are not needed in vitro to form highly active H2-producing catalysts.

  • Coupling reactions of nitrogen atoms represent elementary steps to many important, heterogeneously catalysed reactions, such as the Haber–Bosch process or selective catalytic reduction of NOx to N2. Here, the synthesis and characterization of closed- and open-shell, square-planar iridium nitrido complexes is described, indicating considerable nitridyl radical character for the open shell complex.
