Cover Feature: Hydrogen Isotope Exchange Catalyzed by Ru Nanocatalysts: Labelling of Complex Molecules Containing N‐Heterocycles and Reaction Mechanism Insights (Chem. Eur. J. 22/2020)

The usefulness of ruthenium nanocatalysis in the context of deuterium and tritium labelling of pharmaceuticals using hydrogen isotope exchange is illustrated in the cover artwork. This work includes a detailed DFT-based mechanistic study identifying undisclosed key intermediates and allowed a deeper understanding of C−H (and N−H) activation processes occurring at the surface of metallic nanoclusters. More information can be found in the Full Paper by R. Poteau, G. Pieters, et al. on page 4988.
