The cover picture shows the two principally different pathways in transition metal‐catalyzed hydrogen transfer: 1) a metal monohydride mechanism (right‐hand side) and 2) a metal dihydride mechanism (left‐hand side). Hydrogen transfer from an α ‐deuterated alcohol to a ketone was used as a probe to distinguish between selective (bottom right) carbon‐to‐carbon hydrogen transfer (metal–monohydride mechanism) and non‐selective (bottom left) transfer involving both oxygen‐to‐carbon and carbon‐to‐carbon hydrogen transfer (metal–dihydride mechanism). Two different hydride intermediates, one for each mechanism, are shown as representative examples (top). The latest findings on the mechanism of metal‐catalyzed hydrogen transfer from alcohols to ketones are described in more detail by J.‐E. Bäckvall and O. Pàmies on p. 5052 ff.
