  • Coordination of benzene by a tungsten complex can minimize the formation of oligomeric aromatic products in Friedel-Crafts Arylation. Here the authors show that coordinating benzene to tungsten through two carbons (dihapto-coordination) enables a rarely observed double protonation of the bound benzene, allowing its subsequent coupling to a second arene without the need of a precious metal or Lewis acid catalyst.

  • Cyclohexene isotopologues and stereoisotopomers with varying degrees of deuteration are formed by binding a tungsten complex to benzene, which facilitates the selective incorporation of deuterium into any position on the ring.

  • Interfacial polarization influences catalytic reactions occurring at solid–liquid interfaces, but its measurement was previously limited to conductive materials. Now redox-active molecules enable electrochemical potential measurements of metal catalysts, even on insulating supports.

  • Although interfacial proton-coupled electron transfers are critical reaction steps in chemical and biological processes, studies investigating these reactions are complicated by surface heterogeneity. Now, interfacial proton-coupled electron transfer kinetics are studied and modelled at isolated, well-defined active sites to provide a foundation for understanding complex reactions involved in energy conversion and catalysis.

  • The mechanism by which bimetallic catalysts can outperform their monometallic counterparts is often unexplained. Now nitrate hydrogenation on bimetallic catalysts is shown to proceed via the electrochemical coupling of hydrogen oxidation and nitrate reduction half-reactions, each of which occurs on one metal component.
