  • Beschreibung: <jats:title>Abstract</jats:title><jats:p>The hydrogenation of olefins, styrenes, enoates, imines, and sterically hindered tri‐substituted olefins was accomplished using the pre‐catalyst dilithiumbis(cycloocta‐1,5‐diene)nickelate(−II) (<jats:bold>1</jats:bold>). The mild conditions tolerate hydroxyl, halide, ester, and lactone functionalities. Mechanistic studies, including reaction progress analyses, poisoning experiments, and multinuclear NMR monitoring, indicate that a heterotopic (nickel nanoparticle) catalyst is in operation.</jats:p>
