Summary:The activation of CH bonds has revolutionized modern synthetic chemistry. However, no general strategy for enantiospecific CH activation has been developed to date. We herein report an enantiospecific CH activation reaction followed by deuterium incorporation at stereogenic centers. Mechanistic studies suggest that the selectivity for the α‐position of the directing heteroatom results from a four‐membered dimetallacycle as the key intermediate. This work paves the way to novel molecular chemistry on nanoparticles. Verschiedene Verbindungen, wie Amine, Aminosäuren und Peptide, können in Gegenwart eines Ruthenium‐Nanokatalysators unter milden Bedingungen enantiospezifisch C‐H‐aktiviert und deuteriert werden. Berechnungen ergeben einen viergliedrigen Dimetallacyclus als Schlüsselintermediat und zeigen, dass die kollektive Bewegung von Oberflächenmolekülen durch Modifizieren der lokalen elektronischen Struktur die C‐H‐Aktivierung erleichtert.
