      The cover picture shows the reduction of protons by illumination of a catalytic mixture containing a cobalt-based water-reduction catalyst (WRC), a rhenium(I)–alkynyl photosensitizer, a proton source (H+), and a sacrificial electron donor (D/D+). The final product, hydrogen gas, stores the energy of light in its chemical bond. Their electrochemical and luminescence properties make alkynylrhenium(I) complexes excellent photosensitizers for artificial photosynthesis. In this study, various ReI–alkyne complexes were prepared, characterized, and subjected to photocatalytic proton reduction experiments. Details are discussed in the article by R. Alberto et al. on p. 3002 ff. For more on the story behind the cover research, see the Cover Profile.

      Thumbnail image of graphical abstract

      The size of the bridging ligand controls whether N-heterocyclic phosphenium metal(0) chlorides [MCl(NHP)]n (M = Pd, Pt) form dimers or trimers. The oligomers resist attempts to exchange bridging NHP units, but easily undergo displacement of the chlorido terminal ligands. This reaction can be employed in a catalytic synthesis of formaldehyde dibenzylthioacetal.
