The Cover Feature illustrates an electroreductive nickel platform as a rail system, where a central Ni “switch” directs the fate of alkynes. By tuning electrochemical conditions, the same substrate is selectively routed to alkenes through a non-NiH ECEC-type semireduction pathway or to alkanes through NiH formation. More information can be found in the Research Article by I. Choi and co-workers (DOI: 10.1002/cssc.202502632).
